What difference will you feel on the street between heads with 2.02" intake valves vs. 1.90" intake valves? I can't decide between the AFR 165's or 185's for the street. It's a 331. It might get a 9 pound procharger in the future, but for at least six months it'll be N/A. If anyone has has felt the difference driving a car with one and then another car with the other. Let me know. I'm afraid of losing too much on the bottom end of the powerband
