Theres a whole bunch of guys on the corral with those heads, and if I had the cash then I'd definately have a set.
One guy just recently over there put ~350hp to the wheels with AFR165's, ed curtis custom cam, performer RPM intake, 75mm TB and misc other stuff. This is all with a 10:1 306. This thing is in perfect tune though. Most other guys with this combo see about 320rwhp or so, which isnt too shabby for a N/A 302/306
