ya i would run it stock shimming. but if you want to ad shims start off with one or two .001 shims.just keep an eye on the piston dome. if you see pitting or it starts to look pitted then add a shim or two. this is what detanating is. you can also check your deck hight and post it on here and someone can tell you if your close or not, but i think you will be fine with 30 and stock shimming. good luck,have fun
