Thats really good power and torque for such a mild cam.

My only advice is that if you spend about an hour or so relieving/radiusing the branches of the LOWER plenum of that 2D you will probably pick up some power up at the top. The upper plenum as cast flows about 30CFM on average more for each port than the lower plenum, and it doesn't really take that much work to get them to flow much closer to even. Of course It might not make as much difference on a mild torque motor like yours but on my 6800 rpm 517" it was well worth doing.

I had a very similar 508 RB before this one with only ported Stage V iron Heads (flowed on par with Edelbrock RPMs) and that thing was a HOSS
