Lift is .704 net - 114 lsa. Spec’d to peak @ 6k and carry to 6,300. Heads flow approx 10-15 % more than the promaxx 340 cnc version. Should make 750 @ 6k. Possible more if the heads perform well allowing to peak out at 6,400 and carry from there.
You should have a torque monster with those heads - int runner. The lobe family from comp that icdedppl used would something to consider especially if your going SC. I’d just step up the duration a few degrees with your stoke and CI. Or the same. With superior flowing heads you can ease on the duration and let the heads do the work.

Tks Dynoed at 850 at only 5200 rpm due to old ignition and just 4 lbs of boost now has MSD 6A set at 6000 hope to top 900 with new heads cam might add another 20 what's your thoughts.

Just went back to OT. Mega blower great blower but personally wouldn’t put on anything much more than a 502. But yes I get it…. All comes down to lots of $$$$
