Help with cam selection with 452 heads

Honestly I'd give a cam company a call. You will want to spec something with fast ramps for lower overall duration and to maximize the .050 duration (area under the curve as commonly stated) You will want to close the intake valve as early as possible to maintain compression but still get enough cylinder fill. The 452 heads will be a bit of a bottleneck too. Rusty is on the right track if you can do a solid lifter. Fast ramps, short duration, max lift.
