alright guys, slowly getting my motor back together after being down for quite some time. Tonight I checked the PTV with the cam, and its close. WITH NO GASKET INSTALLED I get the following:
Intake has .033 clearance
exhaust is fine, with .075 clearance.

THIS IS BARE BLOCK TO BARE CASTING. I know the MINIMUM recommended is .080 on the intake, and .100 on the exhaust. So, I know the stock GM MLS gaskets are something like .054 compressed thickness if im not mistaken, but does GM make one abit thicker then that for the LS1 bore?

PS, my cam is a 234/238 .598/.605 on a 114 LSA

the stock GM replacement MLS gasket is .051 compressed thickness, but you should be fine with that one. if you want more clearance and want to spend more, check out Texas Speed, they make a .060 Cometic MLS head gasket.

here is a link to what you need.
