Inliners International Forums General Discussion Engines Is one of these heads better than the others?

Than take the best looking head and work it over.
Use bolt in lumps, install larger valves, hardened exh seats, port it, mill it .030, pull the studs and get the boss's milled down for screw in 7/16 studs. I use BBC roller rocker arms.

Doing these steps alone will add tq/ power to the engine.
