10.7 CR
RPM Air Gap
Performer RPM oval heads
2 inch primaries headers
Roller rockrs/cam with a 304HR comp cams
looser bearings

Your AFR heads flow a bit better, would it make that much of a difference? eventhough I have more lift I still don't flow quite as good.
Theres alot more to consider than just air flow, the AFR 265 does demoralize the RPM heads, esspecially when your only lifting the valve .570. This engine will peak @ 6400 RPM when its all said and done, thats something else to consider, I have not had much luck with the comp hyd roller lobes, remember Ive been developing these exact same engines for 7 years now. I dont think you got hosed, I just know what goes into my engine, and its a little more than an average rebuild. At this point Jarred I think I will ask Harold Bettes to come down and supervise these final tests and write a report on this engine and how it was tested. So stay tuned and lets see what we end up with.
