Id like to have solid 500+. Is there anything you would change there. Ive done my best to match things up. I posted the whole build below. Do you think everything is matched pretty well and will work together?

I think it's closer to 450 than 500+. Much better pistons are not much more money and that cam would like them. However if you need to use them, make sure the block is square decked far enough to get the pistons .015" proud (sticking out) of the deck. Run the gaskets 440Source says to. Have the heads milled .040 (on intake flange too) to get the chambers down to 80ccs. That will give you just over 11:1. I think with those minor changes you should reach close to 500hp if not a hair over.

The Stealths are already 80cc now with there new redesign. If I did my math right on one of them compression calculators. I will already be at 11 to 1 since they have a +7 cc top. I was thinking I needed to double gasket or do something to drop compression.
