Cuda-Tim did.

A spring height mic will tell you the springs installed height on each valve. If it's too much then you would put the shim under the spring or spring cup.



Yes, I mentioned a lower retainer...

My mistake...

But here is a another question. So I just put a shim UNDER the spring, if I need less height? Won't that cause "undue wear" to the shim?



Really the reason your checking height is so you know how much spring pressure you have.( If you have a spring tester) Even if you don't, at least your know the height and you can take the springs somewhere that does have a spring tester. Hope this helps. If you have enough spring pressure, there's no reason to shim. If not then use some shims but you have to make sure your not getting into coil bind, and by knowing the installed height you know how much room you have till spring bind. very important.
