A key factor in this running in process, and how it applies to the OP's question, seems to be how finely were the bores on his engine honed, as all of the talk seems to relate to new engines. Have reconditioners caught up with these improvements? Obviously Toda has, but what sort of difference would it make to using this method if the bores were'nt up to this standard ? (I was going to say "scratch", but thought that just didn't sound right).
