Another possibility is the pre load was light and the
push rod came out and slid in close to the shaft
giving you alot more lift and it hit... check with
him to see what the P to V clearance was... also I
wouldnt pull the engine(yet)... I would pull that
head then roll the engine over so the piston starts
down and then push on the piston to see if it moves
down to check for a bearing issue




I think the Magnum heads have guide plates, and are similar to the chevy ball stud design, so I doubt the rushrod came inn close to the vulcrum, but It could have. Especially when things get bent.

Sorry to hear that. Makes me more and more nervous to read about this stuff when My new bullit is sitting on the stand waiting to run.
