All sound thinking, but still I'm just wondering if you had the basic 350 warm over, +.030 bore, .450 lift cam (oh hope I didnt stub my toe there), aftermarket intake and vanilla flavored 4bbl holley wth headers, and you had two pair of heads to work with, one with 1.94's and one set with 2.02's, would the mild build favor the smaller valves, or would you bolt on the 2.02's. I know there is a well established formula for carb size, but what about valve sizing? We talk alot about compression and chamber cc's here, but how about the valve sizing speech. If there is a good thread on this subject, I just havent found it yet, cuz I know you guys got it down cold. Pardon my ignorance, just trying to learn from those with the knows.
