Looks like a pretty stout race motor. You must be running a mammoth camshaft with your max torque at 5500. Probably not ideal for him though. I'm running a set of 325 Dart Pro 1's on my 489. For his goals your heads are way to big and so are mine. We also need to know if he wants to use power brakes. For a street motor with those hp goals in mind, I'd take Franks advice and go with a good set of budget oval ports. Those GM heads would be fine as well. The camshaft needs to be matched to your rear gear, brakes, and goals. I'd also make sure the camshaft has a pressed on cast distributor gear so you can run a regular gear or melonized vs a bronze gear for longevity. Basically we need to know more.
