any benefit to swapping heads?

30* seats were stupid back in the day. They are even more stupid today. I wouldn't put a 30* seat on a picture of a lawn mower.

A 2.02 valved head won't kill the bottom end so bad you can't drive it. That's rediculous.

The OP doesn't need bad info.

I was under the impression that with 30* seats, you got better flow at intermediate lifts. If I remember right, I picked that up from watching a lecture by David Vizard.

Are there any flow tests published with identical heads with the only difference in valve seat angle? I always need more education.

Sorry for the thread derail.
