Who do I Talk to at Oregon Cam Grnders?

What's the talk of the "1 lifters??? Sounds super expensive. Some grinds need it or? ??

The 791 grind sounds right for me. I'd say the compression would have to be healthy for it to perform at it's peak though.

Just boring out 12 lifter bores to 1", not super expensive IMO.

It allows a bigger base circle and/or more aggressive opening ramp cam profile.
