The question here is, how much are you willing to spend? Sky is the limit. You can go with some budget heads ($1200) or go with aftermarket casting like AFR or TrickFlow ($2200+).

By "bolt ons" I assume you already have headers... but intake and TB?
My vote is AFR. I went up there (factory is right up the street from me) and Tony showed us around. Although they produce quite a few heads/models, each one is carefully machined, checked, inspected, and tested. The final numbers show they flow more, the quality of the shop is one reason why.
My buddy here at work bought a set and Tony hand ported them. His 'old school' 383 gen 1 is making over 500 hp.
