gasket information. I'm researching head gaskets with a 4.410 bore. The smallest compressed thickness in a composition is .039, that gets me 9.34:1 cr I can get a cometic @ .030 that gets me 9.5:1 cr (where I would like to be for the cam I'm useing) but they are $85.00 each. I can not find the right, shim type gasket, with a 4.410 bore. I like the idea of the composition gasket. Would the difference in compression be that much to notice when the cam recommends 9.5:1 cr?
