Yes,see and hear about it a bit but the question I ask is what is the trade off with power if intake closing and exhaust open points are out to lunch?.1980RS wrote: ↑Thu Jul 21, 2022 2:53 pmI know people running 12:1 with pump gas but all of them said the cam opening and closing points were the key to making that work.BobbyB wrote: ↑Thu Jul 21, 2022 2:38 pmWhat if we have a 53cc aluminum head on a 350ci engine...What gasket thickness is called for for 93 octane for a street strip dual plane wit 280 degree seat to seat cam?

An increase in clearance will substantially reduce squish velocity. Squish may have a greater effect on performance than CR.
If you crutch compression with a big cam it must narrow up the power band window so to speak which has to include additional reversion issues especially when piston is heading the wrong direction.
