I'm putting 2.02" valves in 360 heads ...

Notice the big top cut in that picture? The biggest flow killer I know of, the biggest pressure recovery loss there is is not getting a top cut .100 wide where you can get it.

I'm trying to decipher what you're saying here. Is the top cut the 30* angle seat cut in this pic?

The 30* cutter I've ordered is 2 1/8" in diameter. I'm hoping that'll be enough to get a decent cut. My worry is that it'll be too big and interfere with the chamber wall.
