RE: 4.6 PI HEAD SWAP
everywhere i've seen, the heads are like 300-400 brand new, the intake manifold is another 200, plus the head changing kit (gaskets and such) is 100+, so thats up over a grand right there.

RE: 4.6 PI HEAD SWAP
All this talk about the C/R being between 10-10.5 isn't there a way to get a thicker head gasket to keep the C/R down a bit. I'd like to throw some sort of boost on down the road wheather it be nitrous or sc. I don't want to do this project if it's going to restrict me completely, there's got to be some sort of solution for this problem.
Also, has anybody tried an aftermarket cam with this swap? I know there are issues with the clearance with the pistons but I'd like to know if there is any mild cam i could use without having to change pistons.

And Cometic is the head gasket you want if you need to lower the CR.
