easiest way is a set of Edelbrock heads and a cam. I made 475 hp with .573 266@.050 400" on pump gas. So in a 455 no problem. You can port the 4x heads but you'll have almost as much in them as a set of E-heads. I have a 400 block with a 4.250" stroke crank. I make 600 hp with a ported set of E-heads and a big solid cam on pump gas.
