FWIW the intake lift is .613 and Exhaust is .620. Not that it means much but the duration is @.050 227 Intake and 235 Exhaust. My pistons do have valve reliefs in them and I've been told the valvetrain is up to the task. Should be interesting. Got the heads back from the machine shop today. Impressive work. Beautiful surface finish on the deck and nice cuts on the valve seats. These are late model ls1 corvette heads don't know the casting number off the top of my head. Gregories machine did the work, the pictures don't do them justice. I was really impressed with the work
