Guys...planning on putting a fresh set of heads on a fresh rebuild of a 289. I need to know the mods required for the change. I assume the intake manifold has to be changed (for a narrower one) and push rods elongated, and pistons have to be changed so the valves don't bottom out. What else?
Also, any recommendations as what parts are best. Feel free to chime in, this is gearing up to be a Boss 302 clone engine.
