Pocket porting the heads and a little polishing will do wonders for peformance even with stock valves, gains in HP and tork, these poly heads flow better than most and pocket porting will just make them flow more. Poly heads with 2.02 intake and 1.69 ex valves with out preform the later LA 340 X and J heads with the same valves, however, for the poly those valves are not off the shelf parts.
