Well my thinking is especially with guys that want to buy their own valves is a 2.02 and a 2.055 cost the same right? The throat is already on the large size right? The valve job on Edelbrock and Speedmaster heads kinda suck from the factory right? Most guys what a local shop to check their heads out so I’m thinking for about the cost of a competition valve job if they could possibly pick up 15cfm would it be worthwhile. Is 15cfm there to grab. Just thinking outside da box.
