340 Aluminum Head, Rocker Arm Upgrade

The main purpose for me to go with 1.6 ratio rockers is because I am preventing this project from spiraling away from me. What starts as replacing the intake goes to replacing the heads, rockers, then cam, timing set, bearings etc. Before you know it, you're rebuilding the whole thing, which I don't want to do. So I'm forcing myself to leave the shortblock alone at present.
