Dart blocks, dart single plane intake, not sure on compression yet but possibly 10:1, hopefully lower though and Holley carb

Will the heads be ported and flowed? Out of the box they are questionable and need a little help. Don't get me wrong they are a fine head. I have them myself on 496's and will probably use them on my new 555's. There are a lot of off the shelf cams. Surprisingly howards has some pretty good choices over others. I'm looking at some 236/242-670/660 on a 112 that is similar cam valako is currently using in his 555 making 785 hp at 6,000.

I doubt head porting is in my budget.

I understand. Gellner Racing was pumping out 540's with your combo including out of the box 310 heads and a 244/248-640/648 on a 111. Pretty conservative package making a respectable 650 plus hp. If you'd like cam card pm me.

If Jim V is making nearly 800HP at at 6000 from a 555ci, with a shorter cam than a 525 EFI cam, I need to get on his program. I've seen full CNC ported 572/598 combos, with a ton more cam, barely make that power.

I just want those guys to calibrate my dyno.

Actually 565. My bad.

Bob is not God, I learned that when my cams are horrible for my combo... 630 hp with a 540 and Afr heads with bobs cam... By far not impressive at all!

Wow that's a smaller cam then mine and I'm over 100 hp off!
