Northwind, 1050 Dominator, and a 255/263 @ .050 .650 lift solid roller. Ran a best 10.98 at 122 mph in my 3800+ lb 68 GTO. Took the E-heads off and installed a set of KRE High Ports with no other changes. Compression was 10.6 with HP's. They have 2.20/1.7 valves. Ran the same times as with the E-heads.

What RPM did you turn the engine with the E heads and what RPM did you turn the engine with the KRE heads?
