Best Bang for the Buck Head???

You don't need aftermarket heads to run in the 12's. My buddy just built a .030 340 with trw 10:1s, a MP .474 cam, air gap intake, J heads that were not ported, just had 2.02/1.60 stainless valves put in, and against common sense the guy pulled the LD340 and 750 DP off the car and put a performer and a quadrajet on, it still put 317hp to the rear tires. That'll put pretty much any a body in the 12s.
