371 build W/Big Mouth heads

Problem is every flow bench is different.

I know from heads that have been tested, hughes numbers are always higher than the benches I've seen them on. Usually in the 15-20 peak range for discrepancies.

Much like enigne and HP, CFM drags people in and sells product.

I am going thru this now with my big block max wedge victors, I sent Hughes the heads for their monster max wedge cnc porting and their numbers are well exaggerated to actual results. they claim 397 cfm at 700 and my heads after the cnc are showing 346...
