    .002-.003 is fine in a round hole with no taper. I usually true up the hole with an adjustable ream as most are pretty nasty.

        Dap, You are probably aware of this, but I thought I should add some info. You should put some lube, light oil or my preference, spray press fit lube, to the guide and head before chilling the guide and warming the head. This will help the guide find the path and prevent galling.
