Dave thats what i figured, just keep datalogging. Just wanted to make sure i wasnt missing something, still a fresh fish lol. Roadknee its nothin special. Its how the heads came so i dont know specifics because it was a junk yard engine. Looked like they were gasket matched and had the swirls worked out smoothe as far as i could see. They were definitely punched out for the valves too. Which all sucks cuz i wanted the sworls and 1.90 valves lol. Keep velocity and torque up.
