Default Gasket Question
Anyone know which gaskets to use for a LS2 402 with L92 heads?? I tried 6.0L truck gaskets and it appears we're getting some combustion blowby. It's steaming out of the VC breather.
Are the L76 or L92 6.2L gaskets the way to go????????
I tried a search and didn't find anything definitive.

Default FelPro 1161 or 1041
I'm installing FelPro 1161's (.053 thick) on mine. The local shop swears by them. He also said the Fep Pro 1041's (.041 thick) would be ok.

I'll know after the Caddy lifter arrive at SDPc and the turn them around!

The gasket should be 4.065 or more 6.2L. The 6.0l gaskets will interfere with intake valve, I think.

Are you sure that "steam" out of the breather isn't oil mist/residue? 99% of people's breathers smoke.

That's what I assumed as well, but Mike and the guys tuning agreed that it was a little excessive for the "normal" steaming...
