I HAVE A PAIR OF 572-13 365 CNC HEADS FOR MY 580" MOTOR.INDY SAYS THEY FLOW [Email]395@.700[/Email] 399@ .800. I HAD MY SHOP CHECK THEM FOR ME,AND THEY ARE NOT CLOSE.THE SHOP SAID THEY HAVE ALOT OF SWIRL IN THE HIGHER LIFTS.THEY ARE NOT DONE YET BUT THE PRELIMARY NUMBERS ARE 369@ .700 AND 360@ .800.WE ARE GOING TO CHECK WITH INDY TO SEE IF WE ARE MISSING SOMETHING,OR NOT DOING SOMETHING RIGHT.MY CAM WITH 1.7 ROCKERS IS AT .800" I CHANGED FROM 1.55 TO GET MORE FLOW.DID NOT EXPECT THE FLOW TO DROP.DO ANY OF YOU GUYS HAVE ANY REAL WORLD FLOW NUMBERS FOR THEESE HEADS? DO THEESE SOUND RIGHT? THANKS FOR ANY INPUT.
