I have a 1993 Merck Cruiser 3.0. The cylinder head rusted through. I replaced it with a brand new cylinder head but the new cylinder head came with a piece of paper that says 'requires self-aligning rocker arms.' It turns out the new cylinder head push rod holes are too big and don't locate the push rods like the old cylinder head. Can you give me a manufacturer and part # for a rocker arm that aligns off the valve that will work for this engine? I tried using my old rockers but they move around too much.
