Heads are Back from Treatment/Coating

[FordNut]

Picked up the heads and associated parts today. The heads got cryo-treatment, then exterior surfaces were painted with thermal disperant coating, exhaust ports and combustion chambers were coated with ceramic thermal barrier coating, and cam saddles were painted with dry film lubricant coating (teflon coating like used on piston skirts). Prior work included porting, bronze guides, hardened seats for oversize valves, drill out oil drainback holes.

Hard to see the teflon coating in this view.

Here's a closeup.

Here's a cap.

This ought to reduce friction and prevent galling. I never liked the idea of the cams riding on these aluminum surfaces with no bearings.

Here's the intake side showing the black thermal disperant coating.

Here's a closer shot of the intake port if you missed the previous head thread.

Here's the exhaust side.

And a closeup of the exhaust port after ceramic coating was applied.

Here's the combustion chamber without valves, showing the ceramic coating on the chamber and exhaust ports.

Here's what the combustion chamber looks like with the valves installed, all ceramic coated.

And the valve stems are teflon coated too.

The valves are Crower 1mm oversize on both intake and exhaust, stainless steel, cryo-treated, and coated. Here are the faces again. I must be getting old, there's a lot of wrinkles on that hand.

Here are the springs, they're Comp Cams beehive springs, cryo-treated then REM polished.

Brand new rockers (followers), REM polished. Retainers are not shown, they are steel and were simply cryo-treated. Went with steel because I was advised they would be better for street use. They didn't need treatment, but I had the shop just throw them in with the rest of the stuff.

Cam chain & sprockets, cryo treated and REM polished.

Cam drive chains & gears, crank gear, cryo treated and REM polished.

Billet trigger ring, cryo-treated and REM polished. Didn't need the treatments, just went ahead and threw it in the box of parts I took in.

Billet oil pump gears, cryo-treated and REM polished. I already had a MMR oil pump with cryo-treated gears but decided I shouldn't take any shortcuts on the oil system. The MMR pump is re-valved and o-ringed for higher volume and pressure than the standard Cobra pump, so I'll just swap these gears into the MMR pump housing.

Nice Brian!
We'll be watching for your progress!

[DEFYANT]

That is awsome! Very nice!

[glassman99]

Fun Ford 07?

[Seneca]

I have one word... Sweet!..

[Loco1234]

Wow whats the cost on a Cyro job like that...
Is it really expensive...
I'm a little to far in my rebuild to back track and do that...
...or am I hmmm... Its not together yet...

Where did you get it done.....
Maybe I need to get myself a gift for the holidays...
LOL

[juno]

Awesome Brian! Where did you get the work done!

[Joe Walsh]

WOW!!!!.....:bows:

That is a sick set of cylinder heads.

That folks is the way to do it...

1: Keep as much heat where it belongs...in the combustion chamber. Thermal Barrier coating

2: Minimize friction, drag and wear as much as possible. Dry Film lubricant

3: Maximize the metal's strength. CryoTreatment

You've done all the mods and treatments that were on my wish list when I built my engine, but was $$$$ limited.

I could only afford to coat my piston tops with the thermal barrier and the piston skirts with the dry film lubricant coating.

All that plus thermal disperant coating on the exterior surfaces to help them run cooler. Only one other thing to do would have been the oil-shedding coating on the interior surfaces to help oil drainback. The coating shop and engine builder advised against it for a street car because if by chance something flaked off & entered the oil system it could cause serious problems. For a race only car that is frequently torn down it would be ok.

I found a shop that does all the cryo-treatments, does REM polishing, thermal coating application, powdercoating. They're in the ATL area here: http://www.evansperformance.com/home2.html

I had coatings and treatments done on a lot of parts and didn't get a price breakdown on everything, so I can't say how much was spent on the heads themselves. A LOT.

Did you take a look at those (ridiculously expensive) Jesel roller rockers/followers??

I'd love to add them to my DOHC, but at $90.00+ each, I don't have $3,000 laying around for rocker arms!....:eek:

Yes, I really wanted a set of them but called a few shops that have used them and was advised not to. For half that price I would have considered it anyway.

I figured since the Pro 5.0 and Outlaw cars are making 1200-1500 hp and using the stock ones they should be adequate. But I did take a new set of the stockers and have them REM polished as suggested in the SHM modular book.

I'm curious: what were their comments on the Jesel rollers???

[FordNut]

PM sent...

[JVJ]

"GREAT" That looks good.

[ckadiddle]

Ummm... I am glad some of you guys know where all those thingies go.....:)

Highly technical term...

[frdwrnch]

Super impressive! Hi Tech sollutions to age old problems. Just like retuning a stock PCM for HP, perfecting exsisting components through better manufacturing techniques builds the better mousetrap (or RATTRAP)! I did not know some of these processes were available. Too Cool! Thanks for the link. Good luck on your build, looks like you're definitely on the right track.

[MarauderTJA]

Brian, awesome work. I really like the cryo treatment on the parts, in particular the cam sprockets. I am looking at billet steel sprockets but are pricy at $800. for the set. What is the cost for cryo treatment on the sprockets and time frame to get them done? Curious. Might be worth the wait to get the sprockets, chains etc cryo treated rather than get the billet sprockets.

Looks like a super engine plan is comng together. Can't wait to see it all finished.

No itemized bill, so I can't say exactly how much an individual part cost. I'm pretty sure the cryo-REM treatments and purchase price for the new gears, sprockets, and chains was less than $800. I take it that's the price for gears only.

[MarauderTJA]

$800. I take it that's the price for gears only.

Your right. They are used for 4.6 engines that can rev up to 9000 RPM:eek: . Not doubt they will hold up, but pricey. I'll call Dan tomorrow.

[FordNut]

Did you get ahold of Dan?

Just got a call from the machine shop, heads are together. Can't wait to see them. I'll get some pics of them the first of next week and post them. Maybe the short block will be together next week too!

[MarauderTJA]

Did you get ahold of Dan?

No, I have decided to go with the steel sprockets....Cool on your heads being finished. Won't be too long before you will be getting that monster in your car.

Since the combustion chambers got worked, I figured I should get the CR re-checked. Original specs should have been 9.5:1 with the 16 cc dished pistons. I expected it to be a little lower since some material was removed from the chambers. Chambers measured 50cc, I'm not sure what stock chambers are. The block (& head) decking more than made up for any chamber volume changes, the new CR comes out to 9.8:1 which still suits me ok.

[SergntMac]

OEM stock combustion chambers are 52cc.

Hope this helps.

[FordNut]

Thanks. I guess surfacing the heads took them down a couple of cc's

Hey brian: Lookin good...I used to port and polish race heads for a living and could not help eyeballing your work and it looks like a small portion of the bronze guides were cut out to maximize plow...Also it looks like a pretty good bit was removed from the pockets...Nice work...Whom did the porting and what kind of $$ do they get these days for that kind of work..

Thanks for the compliments, yes the porting shop cut the guides down for increased flow. This job was a lot more extensive than what I asked for, but I'm not complaining. The engine builder subs out his head porting work but does all the rest of it (seats, guides, assembly, setting installed height, etc) in-house. The porting was $900.

Check out ProLineRaceEngines.com in Woodstock, GA. They're doing my buildup. Eric Dillard is the owner and his car won the outlaw series race last week in Limited Street class, running in the 4's @ 160+ mph in the 1/8th. One of the cars he builds is Tim Lynch's and he won the Outlaw 10.5 race at the same event, running in the 4's @ 170+ mph.

[LILALLEYKATT]

Hey Brian; I bet that there between 40-50 hrs labor in the port job alone... its difficult to blend 32 air passages equally...Most people dont have a clue as to the time involved...AL

[GreekGod]

I spent probably 8 hours just "cleaning up" the ports and chambers on one 428 CJ head. I didn't have the time or energy to spend on the other one, so it went together with only one side done.

Yes, until you have tried it, you don't have a clue (I sure didn't)!
