Dan, if you remove the cam tower, rotate the shims and re-install it you will find the measurements may change. Adjusting valve clearances on the 907 is a black art. You will not want to do this again soon, so order the shims and shoot for the high side. Throw away any shims that have obvious indentations from wear. They may not seat correctly and clearances could change within a few miles of driving.

When you get them all within range, goop the towers with Loctite 515 and watch all your measurements change again. I made 6 or 7 attempts before settling on "good enough".

May the Lords Of Lucas be with you,
