hey, did you know that they make different size shims. this is what tuning is about. each rocker may require a different shim. get a shim kit with a few sizes and do it the right way. dont mess up the heads or try to invent things. and 5/8 preload is a bit high. you should set it for 1/4 and no more than 1/2 turn. as for noisy, typically valve train mods do give some noise so if its a light tapping sound you hear its normal.
