came up with stock headgasket, stock 243 comes out to 9.2:1
so to bump it to 10.5:1 how much should be taken off? could i get away with 11:1 on pump gas? thoughts suggestions?
so i came up with this calculation:
at .050 off the head it creats roughly a 10.5:1 ratio
at .060 off it creats roughly a 10.7:1 ratio
is this too much to take off? am i wrong with my calculations? would i run into PTV issues with my current cam?
