Good info Dwayne, and thanks for sharing with us. Its amazing how much can be gained from just a little extra work like you performed on those heads. Even if the heads were not worse than untouched stock castings, that would still amount to a substantial gain in power over your basic valve touch up. The resto guys should really be reading this too. Maybe its their pathetic 16 second time slip that keeps them away from the race section...
