Has anyone out there had a problem using a roller cam w/ roller lifters and rocker arms, as far as the push rod holes in the J heads having to be hogged out?
 
Thanks....This motor has been a learning experience appreciate the info..John
 
It's a very common problem and can happen even with a flat tappet cam if the lift is enough. The taller roller lifter just makes it worse.
