Not to disappoint but in stock form RPM heads wont make that kind of steam, the compression is a little low, and I don't believe the intake will make the number. The Victors would. But not RPMs. If I have to estimate using what you have I'd put a realistic 530hp and 550tq. RPMs might get as good as 280-290 out of the box depending on core shift and your shops valve job. If they were not corrected before assembly, figure the 280 number. That should be enough to reach the 10s. But I dont think 10.50s as designed will be doable.
If it's still in process... This is what I'd change:
Have the block square decked to get the pistons .005 proud of the deck.
Have the heads milled .040 and the intake side cut to match to reduce the chamber to 80ccs. Those two changes up the static compression to 11.6.
Have the heads at least stage 2 ported. It's pretty easy to get them to the 300-310cfm range with this.
Replace the intake with either the 440-I4-2D 4150/std port opening dual plane or the Victor 440 intake.
I think in terms of power, the Victor will make more but the dual plane will fit under the hood better (still tall, but might fit with smaller scoop) Thos changes should get you to 600hp.
