Head flow and power differences question / discussion

I just got the results of this build and I am smiling.
I stuck with the Indy heads and went with Holley 550 tunnel ram carbs custom built from Allstate Carburetor.
Molnar 416 stroker kit (418) from @PROSTOCKTOM.

My builder didn’t beat on the engine, just ran it for break in. Nice weather for the dyno.
Looking forward to getting in the car.
