Only thing I don't like is the rocker assembly hangs over the top of the head making vavle covers a PITA. I had to get reverse lip covers and grind 1/2 of the upper lip off to clear the H/S rockers. I'm going to guess there are better choices out there for the money. Most "mopar" products are overpriced. Now if you can get a used set, it's a different story.

That's the rocker, I used Erson rockers, look like the sharps with a set of cast alum. valvecovers. They need a lot of work to get to 330 from how they are delivered. Contact fast68plymouth he has a lot of experience with them.

Only sold mine earlier this year after deciding maybe I could go faster w/ ported Victor heads (not proven yet...) Quote: how much porting do these heads need ? Quite a bit, since out of the box they're really not "ready to run". That includes setting the guide clearance, doing a good valve job, etc. Quote: can you get 330 c.f.m. That's more than I think 95% of the ported Stage VIs (not counting Chapman's CNC'd castings) have ever seen. Figure more like 310+ w/ standard 2.14" valves. There's an archived thread under the OLD Moparts tech articles (linked from front page, not from forum index) that covers some of this stuff from years ago. Quote: and who does the best porting Well, I know who did mine and he's the same person I'd send a set to if I was doing them again: Porter Racing Heads, S.
