Since it is one of the more common valves in use in these LS7 heads which have been done, I think that's a good one to include in your testing.

Noting against the Ferrea valves, just that if there are lighter solid stemmed options out there, then perhaps better to test using them.

4. Torquer cam/PSI springs, stock valves (already tested long ago, but we will baseline again)
5. Torquer cam/PSI springs, solid stainless exhaust valves
6. Torquer cam/dual springs, solid stainless exhaust valves
7. Torquer cam/PSI springs, Ti exhaust valve

Does this still apply to the configurations?

Any graph titled as 'Laser' gets a thumbs up from me.

Looks like the Katech Jason!

Is there a #8 configuration? Can't wait for all the configurations, but my bet is on #7 as the most stable. 7500 rpm stable.
