440 compression ratio

[atb7346]

If I get a 440 big bore kit., what is the best compression ratio for the stock cam rids. I can get a package with teh gaskets, sleeve, piston, and a stage 2 hot cam. What else would I need to replace.

if you get a 11:1 compression ratio you dont have to run high octane fuel. All you need is 91

wouldn't be a bad idea to replace the cam chain and cam chain guides, also check the rocker arms for grooving.
