I ordered a matching intake when I got the heads, super victor efi. All light weight valvetrain, PAC springs, titanium retainers. It revs to the moon.
I was considering going bigger but was talked out of it, because of the heads it was built with. Steve C. had input on the selection. I will have it on a chassis dyno for tuning this summer, should have a closer number from that. I may switch to 1.65 rockers, will have to see.
I have a conservative 2.5 exhaust on it now, but will be switching to 3" tapered head pipes to the mufflers, should remove one of the last restrictions.
Someone could probably run the numbers and get a good idea too if they wanted to. I honestly don't care what the numbers are, it's basically only good for bragging rights, but the dyno would give an idea of what the level of efficiency is. That I am interested in.

Definitely 3" exhaust, preferably mandrel. But you already know that. You should easily get 700 H/P out of that combo.Engine will want 2" headers though and dominator carb like a 1050.
