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...

That's funny! I'm laughing with you not at you. Had a guy send me Hughes Pro-Comp Victor CNC STD port heads awhile back. I flowed them and they were a little better than what they flow OOTB. I sized the port properly, re-valve jobbed it and got them up to 346-347 cfm. 397 --LOL. J.Rob
