Cliff Ruggles can correct me here, but if memory serves me right he used Comp lobes 3315B and 3316B ground with a 112 lobe separation. This on a pretty much stock Super Duty engine build, low compression around 8.5-8.8, nice idle and good vacuum. I believe it produced 457 hp at 5200 rpm.
This does not represent any endorsement for these specific lobes for the OP here, offered more to point out the amount of intake duration used. And the valve lift.
