I have a set of ported Stage VI's on my 440-6. No idea on what they flow, or if they will flow 330. Only thing I don't like is the rocker assembly hangs over the top of the head making valve 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.
