Thinking long term, the problem with higher compression and a bigger cam is that if you ever want to switch to EFI you've just complicated your life. The O2 sensors do not like lead so race gas is out and tuning around a big cam can be a hassle.

If you are committed to your rotating assembly then you might want to pick a cylinder head with more cc. Ported Edelbrocks might be your best bet. Talk to Dwayne at Porter Racing Heads and see what he recommends.
