I have a 500ci. low deck engine that belong to a friend, he always had trouble with rocker arm adjuster screws gaulding to pushrod cup. The engine has original B1s with black rockers that came with heads from koffels. Do I need T&D rockers that oil thru push rods? The engine is aluminum rod,738 lift roller cam. Drag Race engine, Any help would be greatly apreaciated. THANKS.
