Cold Spec is .012-14 if I remember right on the intakes they are all over but one is as much as .017. Exhaust cams are about .03 over spec in the worst case. Basically about 1/3 the valves are out of spec on both intake and exhaust side.
Mystery solved.
I’m having it all redone starting today. IPP has said they will cover the repair. I hope they come through. This was a pretty egregious F-up from the machine shop they use. One valve had a few thousands under lash and that’s actually a bit scary. I’m with a pretty good tech. Hopefully he can get the lash sorted on his first go but there is a little trial and error that goes into this to get the buckets all sorted. Either way after bony J’s of pulling out my hair trying to get the Z back in one piece we are in the home stretch.
Of course I still may have to reflash the VVELs and retune but... baby steps.
