Hey guys, I'm running a fully built S13 SR20 and I just got the block back from being sleeved and I'm getting ready to start assembly. I'm am going to use the Cosworth Head Gasket and I'm wondering what thickness to go with. I have JE pistons that are .020 over that are dished and i'm using HKS 272 cams, any idea's on how thick I should go for the Head Gasket? Thanks for any input!

Are you wanting to change compression ratio?

Well I'm not looking to go to much lower but I did have the head and the block decked so I would rather try to be on the safe side with clearence's.

Just add how much was taken off to the stock size and then you should still be at stock clearances.
