Default GM847 with afr 190cc

I currently have a 226/226,.554/.554 cam with these heads. I have up graded my springs to handle a .600 lift. i also have forged pistons, rods etcI'm spraying a 200 shot through an NX dp kit. I have a th400 and the stall is 4000. Will this came work well with my heads and my combo in general?

Those heads are not great unless ported heavily, mine were worked slightly but still needs improvement.

I think those heads are fine as is. Sure they are not super impressive, but they are much better than than stock heads. There have been plenty of people that have made 350-360RWHP with stock heads and that cam. There will be much to gain with head work tho. I think you would be fine, and the 112 LSA should be fine for the spray too. I say it sounds like a good combination. Should run great.
