W2 Mopar inspection w/RAMM

The Batten heads were the aluminum W2's. and where the W2's came from. From what I remember Batten made Oldsmobile heads. I had a set of oval and square port batten heads. I liked the square ports they were like the Indy 360-1 we have now. W5's were great heads but finding what you need to use them was always a problem with the raise ports.
