I agree with noot on the +.010 clearance. I have taken a lot of engines apart over the years and they were too tight and it causes bushing wear and eats up the shims, whereas the engines with more endplay were fine. Harley specs were too tight. One thing I do on the needle bearing motors is if I have the same number of shims on cams 1&2 or 3&4 is put the shims behind the dogbone if I can. That controls the endplay without putting rotating thrust on the shims, and seems to work well and its the only way to adjust the endplay on the #2cam unless you use the special #2cam shims eastern sells.
