Oil psi was @70 cold 60 hot. Yes all oil gally plugs were installed. I was running the break in oil used by the engine builder not sure of the brand but know it was proper break oil. Its a LA block. Yes. I have serched fourms for multiple issues this being one of them. With retro rollers the geometry is very off. The engine was tested for clearance. I was there that day and no cool bond was evident. Both cams were still below lift specs of eddy heads. Just bad luck? Don't know....
