Well-63-65 cc's seems pretty huge for stock heads-I think they are more around 61 and 9.0:1 compression. Try this website:

You need to know the gasket thickness and the deck height from the top of the piston at TDC. Not exactly sure what stock is but I know the thinner graphite gaskets are .038" and not sure what stock DH is either
