Went back in with new 65mm TB and C&L 76mm MAM kit. Gained 14.5 HP and 9 ft lbs TQ. Timing was bumped and clutch was fine so I guess the GT-40 heads must be killing me.
Twisted Wedges or AFR's will be my next purchase after I can save a little jack in the next few months. I'll post an update after that and let you guys know how it goes.
Thanks for the help!
