This guy's misery is over 8 years old, but I just ran into this EXACT same problem..
OK, (takes deep breath) FYI, I think I have my valves figured out. I have no idea what went wrong with my initial measurements, but I kind of gave up and started over.
I pulled all shims and bought 8 new ones, with a nice selection of smaller sizes. The valves I deemed the tightest got an adjustment of up to 0.25mm (i.e. 2.60 >2.35). I estimated everything else on the thin end and replaced all 8 shims with smaller ones. Some were still tight AF, but gradually I was at least starting to get measurements!!
After assembling and disassembling many times, (approximately 6 total) I was finally able to get 7 measurements. (My smallest feeler is .002") I STILL had to buy three more shims to get everything right. I now have every clearance at either .005" or .006"
I had to mathematically "back into" the original clearances, but they were as follows:
Exhaust (inches) (1234): .004, .002,
-.0037, .001
Intake (inches) (1234): .002, .003, .004, .003
On a side note, the blue Permatex matches the candy lightning blue pretty nicely!
