I believe you will find that a set of -.001 bearings are what you need to tighten up the clearance a little. This is based on a crankshaft that was ground small, say 2.4992" as an example. The same way a -.010 bearing is made for a crankshaft ground to a nominal 2.490". To get extra oil clearance, you would need a bearing marked "X" for extra, or some mark them +.001 for a crankshaft that is too large like 2.5008" for example. Either way, I think both are available. Just a little harder to find for a Pontiac. Good luck with your build. I also wish you had a nominal 2.200 rod journal. I keep STD., +.001, -.001, -.009, -.010, -.011 in stock here.
