Im just wondering, whats all involved in the shimless conversion? If at all possible Id like to do it. I have some 20k STI heads that I have springs and keepers and cams for, but no valves. Since I have everything apart I would like to go shim less since no matter what Im going to spend the cash anyway. Can anyone point me in a good direction? I know that the bucket dimensions and thickness need to be used, but since I have neither, does it really matter? If it does, can anyone post them?
