454 heads 3872702 reworked mostly five angle cut on 2.19 intakes and 1.875 exhausts so far. Stock bore and reworked rods with nice bolts.

What if anything else would you do for these heads for a street machine with planned 2 bolt caps and cast crank only?

Suspect flow 300 or so with compression planned 9+ to 1 flat tops. What would you do from here for cam, springs, rockers yada to pull conservative 450 to 500 hp at 5800-6500 rpm with 750 carb on dual plane hi or low rise like Performer 2 or Performer RPM?

Thanks
