It turned out that my spark plug blow out was because of a cracked head.

Looking for opinions on what route I should take. I am guessing this had to do with uneven cooling since it is the cylinder closest to the firewall on the passengers side.

Thinking about replacing them with some take off's

I'd replace the head. Takeoff's would be the route I'd go.

I believe the cooling issue was with the drivers side head.... not the passengers side.

Have you ever overheated?

Cracked heads are very uncommon on this motor. Usually overheating will warp a head so that the gasket no longer seals.

Do you have any pics?

no the car is still at the dealer who tried to fix the blowout...
Talked to zack and Bodyman is selling a complete engine.

How impossible is it to replace the heads without pulling the engine?

First time I've heard of a cracked head on our motors. Make sure they give you the old parts.

I talked to the tech at ford and he said from what he could see the crack went all the way down the hole the sparkplug goes in

I will post pics of the old engine
