This is turning into quite a bunch of oil consuming "ifs". One thing that I can say, no matter what, check your machine shops work out before you assemble things. They make mistakes sometimes. Tell them the cleances you want things to be, number you parts and where they go, tell them what grit you want your cyliders honed with (consult ring mfg sheet)....and double check their work. If you don't know how or don't have the mics, get somebody else to do it for you. Very important.
