Hey Elmo,
A member had GTM stage 1 valvetrain and headwork along with JUN cams on his Z, plus other goodies. Here is his thread:
John's Sweet NA build You may want to search his thread because it is 29 pages. The tune was on a dynapack with 7500 rpm redline, so it may be hard to compare with your dyno/tune. And if I recall correctly, he no longer has the car anymore. I hope this helps.
