Can someone calculate what thickness head gasket I should buy for a 11.0:1 compression ratio on my motor if I give you the specs of everything? I'm getting ready to buy cometic head gaskets and I need to know what thickness I should get. Here are the specs:
Head cc: 61cc
Piston cc: -4cc
Bore: 4.030
Volume: 347ci
Deck: 2cc

There are numerous compression ratio calculators out there. I used it when I built my 10.1 CC car. Do a google: compression ratio calculator. I used to have the sites but my harddrive crashed and I lost all of my websites -
starting all over again.

Edit: Ahhh found one: www.csgnetwork.com/compcalc.html. There are other automotive and non automotive calculators on this site
