Are the pushrods clearing?
Check'em, after that... might have to pull it apart at least the heads to see the cylinders. And is there a valley baffle tray used? They require Clearancing
Only valley tray is bottom of the intake. Never thought of pushrods rubbing .. what's the best way to eliminate/ check that? And wouldn't that have been there always? I wish there was a Mopar Ear near. Lol
