Quote: First of all the Victor is not that great of a head. On my SF-1020, 4.375" fixture, 28" of water the victors went a best of 317 or 319 @ .650". I was not all that thrilled-so I cut and cut and cut,,, etc. I managed a peak of 357 cfm after many hours of work @ .700-.750" lift. So this engine went onto our Sf-902 and we struggled to make 720 hp and 652 ft/lbs from 471 cubes on pump fuel. To make a long story short the Victors have left a foul taste in my mouth and without the benefit of 13-1+ compression they would have a hard time cresting 800HP on a realistic dyno. As a matter of fact I have a 512 combo going together right now that will have some Stealth heads on it that flow 284-288 on our bench. It will have a hydro flat tappet cam 9.5 to 1 and I expect 550-570 hp @ 5300rpm. The Stealth heads are what they are! A LOT better than 906/452/346 OEM cast junk (oh and inexpensive). J.Rob
