I decided to go to the Track with my son and leave the problems sit a few days. I'll pull the heads today to check for any pieces that might have made it inside of the ports. Now that I think about it spinning the motor with ignition off probably contributed. Bob, do you have any pictures of the pieces you weld in? I like Rat Patrols blow off valve. Anybody know where to get that style valve/plate? It has a MSD 7al2 box w/crank trigger at 32 degrees. I'll check the carbs as well. In fact as long as the steering linkage off to remove the headers Ill pop the pan for a bearing check as well.
