main bearing Q please help

[Gengus]

as some of you might know i am rebuilding my 7m gte. I am replacing the main and cap and rod bearings. i went with a standard set of main bearings from napa. when putting the crank back in i plastigauged my new bearings just to be safe. it turned out the new bearings had more clearence than the old ones and where barely within spec. i really dont know what to do. toyota claims that there are different bearings for each spot and that i have to buy them from them for something like 30 dollars each which amounts to over 200 dollars for just the mains. but then why do stores like napa and advanced both sell all the bearings together for around 40 bucks. some of the bearings are different and the standard set has a few different bearings and you can tell which ones go where. since they did all work and where just not exactly in the range i wanted them i was thinking i could get 10 thousandths or whatever number would make it right oversized (or undersized i get the two confused). if anyone else has experience with this please let me know as i am kinda stuck and would rather not pay toyotas rediculous prices when clevite makes perfectly good bearings.
thanks,
Gabe
