Drill out the holes in the head where the push rods go. Install screw in studs with guide plates. This will fix your problem as far as why the push rod issue. Seen this several times on sbc where the push rod is “guided” thru the head. Once the push rod wears the hole in the head the push rod binds the rocker arm.
