Ok I have a ls turbo cobalt its has the l61 and I know im posting in the lsj part but no one in the l61 is any help. So I'm building my motor full pistons, rods, head gasket, head studs and rod bearings. But i have a cometic head gasket and i have bin hearing a lot of bad things about them not sealing, so what other brand head gaskets have u guys bin having luck with stock or after market ? I'm gonna be pushing 20 psi on my 50 mm precision turbo so I want it to seat properly. And when I put the pistons in should I reuse my stock rings on my sleeves or hone the block and re seat the new rings on my stock sleeves ?? Any help please???!!
