Since I was the OP, thought I'd state the finished version on this build. Ended up getting 452 cfm at .900 and eliminated the stagnated areas of flow. The engine made 1084hp. Not quite the 1100 hp goal but the customer seemed happy.
Did you go to a 2.350” valve and a steeper seat?
Yes I did. The Sweet spot was lowering the floor approach to the SSR

Nice work. They pretty darn good heads then great results
I want to try their new 365 port with the 2.350 1.85 valve combo.

Did you drop the peak height of the ssr or lowered the port floor but left the peak height of the ssr the same?
I dropped the floor to the ssr and blended the transition, effectively lower it somewhat. Doing that you have to constantly flowtest, since it's easy to go too far and lose what was gained.

Did you take a measurement of intake ssr crown height off the deck?
