New gasket and brass shims between the two upper bolts where the gas pedal assembly attaches. The flywheel housing was checked for flat on a surface plate and dial indicator. The entire surface was within .003.
When sweeping the dial indicator by turning the crank everything is within .005 until it gets to the top portion where the shims are and the the dial jumps to .015. The service bulletin said to "add" the brass shims if the housing is not within .006 in relation to the crank flange. My thoughts are to remove the brass shims even though they are meant to compensate for the thickness of the gasket.
Thought and advise please.

You must have the two top mounting bolts torqued down to make the test. These are the bolts that hold the throttle linkage on. Likely you have the linkage off. In this case the bolts would be too long to torque. I keep a pair of shorter bolts handy that I use to tighten the top during the test.
When making the test you must keep in mind that the two .010 metal shims are for the purpose of being even with the paper gasket that is at the lower mounting bolts when all is torqued down. The suppliers sell gaskets that are all over the map in thickness. Most are all too thin. The paper gasket will crush down some, the metal shims will not. What I do is purchase a roll of gasket material from Napa and cut my own. You can buy various thicknesses. I purchase the gasket material thicker than the shims. Usually .015 - .016.
