what size head gasket do i need t make my svt block go from 10.2:1 comp down to 8.5 or 9:1 compressio?

 

[fokuzx3]

use a zetec head gasket if im not mistaken, and it automatically lowers the compression..im pretty sure thats what jeremy did w/ his pw focus w/ the svt bottom end

using a stock Zetec head gasket wouldnt lower the compression all the way down to 8.5:1 would it?

 

[fallacious_focus]

definately not. wouldnt this just lower the compression to 9.6? p2p, why dont you just get lower compression pistons?

why dont you just get lower compression pistons?

Because those cost way more than a head gasket...[giggle]

Talk to McNews about Cometic head gaskets. The stock Ford gasket (all models including SVT) is .027" thick. Some aftermarket ones like Felpro are .040", but that probably only lowers your c.r. to 9.7 or 9.8. Ask McNews which Cometic one you need for 9.0.
