Dan set up some seriously custom WP Sporstman II heads for a SB chevy about 12 years ago for my 1976 Corvette.. They're still making huge horsepower on the street from their original build. If you want cheap go somewhere else. If you want to work with somebody who know what they are doing, talk to Dan Maples in Portland Oregon.
Pros: know what they are doing
Cons: too bad I don't live locally anymore
