AAll this depends on your application. If you cruise between 2000 and 2800 rpms go with Paul if you go 3500 put on the big heads. World makes good stuff, there are better but the boat application it is a waste. With the right package big heads work. My corsican has a 351 Clevland big port heads 2.15 intake valves and 1.85 exchaust valves. It idles at 750-800 (not smooth as silk) will plane at 2200 cruises at 3200 to 4000 and will 5600+ rpms any time I want. This didn't happen overnight, it took a long time to get it exactually the way I wanted it.
