Setup is B18C1 block, wiseco flat top pistons, manley rods, LS crank. I'm running an un-milled B16 head with Skunk2 Pro1 cams, skunk2 cam gears. I don't have any B-series headgaskets here so I can't even throw one in to clay my motor, but I'm thinking of ordering a cometic HG. Do you think a stock thickness HG would be ok, or am I going to run into clearance issues?
