THE HEADS WHERE SET UP BY AFR TO MATCH THE CAM THAT THEY CALLED COMP CAMS AND TOLD THEM GRIND TO THERE SPECS TO MATCH THE REST OF THE MOTOR.I DONT THINK ITS VALVE FLOAT BECAUSE IT HASNT DID THIS THE LAST 20 OR SO PASSES.LAST NIGHT I GOT TO THINKING AND THIS CAME TO MIND,WHEN THE 6AL2 IS BOLTED TO ITS MOUNT THERE IS A STICKER THAT HAS THE REV LIMIT RPM RANGE FOR LOW&HIGH ON IT AND IT IS UPSIDE DOWN.I WONDER IF I COULD BE SETTING IT TO 3700 INSTEAD OF 7300.I COULD BE WRONG BUT I SHALL CHECK THIS OUT WHEN I GET HOME TODAY AND LET YOU KNOW THE RESULTS.
