How 'bout those flakes? Did you see any? It was really hard for me to hear the exact noise in the vid, I even played it a few times but the intake and exhaust made it hard to pick out :(

Oil seemed clean. I'll send it out to black stone this week. I didn't bother pulling the valve cover to check the lifters though. I've decided that it's best to build the engine anyway. Something isn't right and I wouldn't feel comfortable bringing this motor back to the track.
