Good enough is what they settle for, itt seems.
Proven by how well they run
That's true. I believe that Saito wanted the cam advanced 3,75 degrees in this case. Advancing or retarding cam timing to change the power band in performance engines is not uncommon. If Saito wanted the cam timed "straight up" they would have cast the front lobe/gear that way and keyed the rear lobe that way.
Thanks for PM.
