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?



i just assumed you called it the wrong item , i thought you meant a spring cup which is used to locate a spring on a head thats not machined to keep the spring from moving around or keep the spring from eating up an alum head .
