(Every head and application will achieve different flow numbers based on each configuration.) Exhaust @ .750" lift flows approx. 330 CFM and 360 CFM with pipe and perfoemance valve job and finished combustion chambers. Testing was done @ 28" vacuum using a 4.500" bore fixture." Copied from the spec sheet.

We have them priced at 8050.00 for Heads,CNC porting,Ti valves,T&D rockers,Manley thriple springs,Ti retainers etc assembled. The Preadtor combo with the same stuff is 10,050.00 from indy. We have used Indy intakes and have spacers for the B-1 Intake. last I knew on the Best Machine Forum when the heads were first done, it was listed for $9,995 for a complete top end with pushrods, etc. I was unaware that the price has come down in the last two years. and the listing also mentioned a reworked B1 intake to match the PSO ports.
