They could be run as is. I had it running with them before but didn't take it to the track.

I talked to Dwayne Porter yesterday. Think I'm gonna follow his advice and buy a set of Trick Flow heads.

From what I've seen, going to the oversized valves on 915's decreases flow (with out a lot of other work). It shouldn't be that big of a set back to save for the heads.

The motor is out of the car right now anyway. Seems like an opportune time to spruce it up.
