Blowing head gaskets? Heres the Solution?

[MarauderMark]

I was reading trough the march issue of hot rod when i came across this artical.would this be good for our s/ced engines or is this strickly for track cars?If this is for my application then it sounds like a god send..

Sounds like a very interesting technology. If I read this right, its about $200 per cylinder or some $1600 per set plus labor, etc.

However, in reading Marauder Forums for 2 years now, I really don't recall blowing headgaskets as being a recurring problem here. Not being a wrench or a gearhead, I am not sure of the value on an aluminum block. Seems to me that using the gas-filled technology would translate directly to failures in other parts of the engine by transfering the pressures/increased stress elsewhere ---- sort of like that football sized hole in the side of your old engine block.

Cobras are running about 600- 700 hp w/ huge amounts of boost. I dont think I ever hear of a head gasket going..... Good info none the less..

Head gaskets hardly ever go in these engines. I think I've read of one instance. It is almost always the pistons first and then the rods.

Not to discredit your research or home work or any of the parts you've discovered here on the 4.6L head gaskets. But I've learned that 4.6L both iron and aluminium blocks have very serious head gasket retention especially when using stock Torque-to-yield head bolts and totally stock gaskets. I've learned and believe that if you blow gaskets on a 4.6L with a power adder and you've replaced the pistons with forged already.... then you've asked for it with either a aggressive tune or not enough octane for the application or both. Think about it, most 4.6L with a power adder will break a stock position before they blow a head gaskets. This is a pretty good sign of the home work Ford did for head gasket retention on the 4.6L's vs the old push rod 5.0's.

Their is a lot that people don't see that makes the 4.6's have a tighter grip on the head gaskets then the old push rod 5.0's. Things like: equal length head bolts, head bolts that are longer and go deeper into the block so as not to deform the deck when torqued, Torque to yield bolts, An intake manifold design that doesn't pull up on the heads like the 5.0's did, smaller bore circle and head bolt spacing.

This all adds up to work very well.... so well that all we use at our facility is the stock bolts and stock gaskets with incredible success with up to 25psi and the right octane. If you manage to make the gaskets hold up any better, then you'll simply hurt pistons and valves if the conditions would have blown a gasket first.

Yeah, that's what I meant to say !!! :rolleyes:

Fellas thank you for your input and also for answering some questions i had and was wondering about(special thank you Lidio).I know that our cars did'nt really blow head gaskets ,only mine seems to be and was wondering if this is a solution but as Charlie was saying doing something like this would only transfer the damage to bottom end..Thank you for your imput..

Lidio..My company (ann Arbor) manufactures a metrology unit .
It uses multi phase, multi frequency laser holography to measure flatness to about +- 1.5 microns. It has a 12" field of view and about a million data points.We are currently measuring transmission valve body halves ( new 6 speed automatics) to insure sealing for the Majors. We are working on doing cylinder heads and block decks next. I am not an engine builder.
The machine cost about $250k, but I could get a few special parts checked for flatness or a desired profile if it would help or be of interest.
Most improvement breakthroughs are a result of testing and better measurement technology (like the dyno)
