Hi, I am going to be getting a new cam or a regrind, and rebuilding the whole head in general, so I had a question regarding finding the correct lash pad. I understand doing the wipe test etc., however in everything I've read it says to try lash pads until you find the right size. Since I don't have different sized lash pads lying around, and it would be a pain to order multiple lash pads and wait for them, is there a way to shim the original lash pad and find the correct size like that? and then just purchase the set of the size I need? I understand that it is recommended to check every single rocker, and each pad size may differ if the valve stems aren't aligned to the same height. Thanks for any help with this!
