The results are in:superman: +2mph with the Edelbrock E tec heads over the Pro Comp heads:salute:.

The E tech's 200 cc intake port and raised runner Vortec with fast burn combustion chamber against the Pro Comp"s 210 cc intake port and raised runner bow tie with CNC combustion chamber. The intake ports actually are larger on the Edy even though the Pro comps are 210CC. Edelbrock also CNC the ports to qualify the spacing and size, and the exhaust port is larger:yes: I'm up to 72 MPH :biggrin.:
