Not Ranked
You never replied to the question about asking if the heads were CNC ported or are out of the box. Which is it? If the heads aren't CNC ported, don't bother putting the engine on the dyno. Either swap them out or send them off to be ported before completing your engine build. Judging by the parts list, you are spending a lot of money on some high end parts, especially the bottom end. Heads and cam are the two components in this package that creates all of the power, do not spend a fortune on your motor and let those two pieces hold you back. The cam sounds a little small, and I would suggest that you will want to change it out if the motor does not meet your power goals. So, just change it now and since you are buying a carb, go ahead and get an HP 950 and then if you don't like it by, a second hand vac secondary carb off of Craig's List or e-bay, cheap.
Non ported heads and current Cam 485 hp / 510 tq
Ported heads and current cam 535 hp / 540 tq
Ported Heads and bigger cam 589 hp / 545 tq
