Brian. This part of the reason for tipping valves. GENERALLY ive found theres around 40/1000 that can be taken off the stems which leaves 15/000 for contact on the spot inside the buclets. Most stock first run shims are in the 270 range. Shims go up to 315 in my factory kit which will never be used generally. Tipping makes use if the thickest shims and saves all the middle range ones.
Second reason was this head was in atrocious shape as the picture shows. I had to cut a lot of material off the seats so that made tipping them a necessity. Only2 were good so i left them alone.
I will take pics and post my madness on the first one i do. Im planning on getting the shop cleaned up tomorrow and then starting the reshimming on the bench.

My test shim in each valve was a 240. Regardless of what the original shim was i put in a 240 and came up with what to tip each valve. Here is the data from intake 1 as the example of what i went through for each valve. All valves are now good clearances. I used one 290 from the shim kit. All others were take offs i saved from other adjustments or salvaged from old heads. I didnt take a pic of the final spreadsheet.
