They are the stock heads that came on the motor. The machine shop billed me for milling them, but I am not sure how much he took off, and that could be part of the problem. THe first set of tubes that I bent were the comp cams 289/302 which were longer than the Edel recc ones. Since I installed the shorter tubes, the motor had been running fine, until this stupid roller crapped out. I have a replacement on the way, and when it gets here I will be able to determine if there was any other damage. I have NOT been hot rodding the motor, I have been trying to break it in nicely, so that I can dump the clutch later with a clear conscience. But, when or while, the roller was crapping out, I had a BAD knock going on. I don't know if a valve may have stuck, or WTF. I guess I'll just have to wait and see when the new roller shows up. By the way, it was a proform rocker. They are less expensive than most. I'm hoping this was a unique experience, and that the rest of them don't crap out later!
