The cylinder heads are out of the box Victor 440 heads. There is no port work done at all to the intake or cylinder heads. We've done MaxWedge ported Victor 440's, and for a street engine with an operating range of no higher than 6500 RPM, the untouched heads produce the better numbers.

very nice this is the first dyno ive seen with the new victors was there alot of work done to the heads?
