thanks, makes sense
What is the relationship of intake and exhaust port sizes to the size of the combustion chamber. What I mean is GT-40X's with a 58cc combustion chamber flow 240cfm @ .550 lift utilizing 1.94" intake and 1.54" exhaust valves. While the afr 185's with a 58cc combustion chamber flow 273cfm @ .550 lift utilizing 2.02" intake and 1.60" exhaust valves. Are the AFR 185's with a 58cc chamber overkill? Do you need valves that big with this size chamber? Better yet, what is the maximum size valves neccessary to fill a 58cc chamber on a naturally aspirated motor? Could an intake keep up (any brand)? Or is that even the point?
