How many brands use the same shims? I'll buy that hotcams set but if there was an S&S kit for Harleys for half the price well...
-1 for not needing the kit. He is starting out new. He will have to try shims until one works.

My opinion: Get a kit. Put a small shim in and see how tight it is. Try till you get within speck.
When you are checking a motor during its periodic mantainance, you have the advantage of KNOWING which shim to use. There really is no way to measure short of putting a shim in and using a feeler gauge. So unless you live next door to a shop or they will give you a hand full of shims to try, I suggest getting the kit. Especially if you live in the boonies like many of us do and don't have a close local shop.
