A street car with a 500 hp big block application that will see 6000 rpm max, would the extra expense going from 3/8” to 11/32” valve stems be worth it?
Details of heads. 781 heads, installing Manley stainless 2.19-1.88 valves with mild bowl blend, .600” max on cam lift.
Would I need the street flow or race flow series of valves?
