I'm not an expert, but since you haven't gotten too many replies I'll chime in. That sounds pretty loose for rods to me, I'd think your oil pressure would end up pretty low even with an HV pump and 20W50 oil.
Are you sure you have a standard .030 under bearing in there? As mentioned perhaps the rods need resizing. I'd shoot for more like .0025-.0030.
That's awful loose.
Double check everything. Then shoot for the .001 per inch of bearing journal plus .0005 which should put you at .002375 to .002875, or .0024 to .0029. If you are in that range, that will be fine. Just be sure and have full torque on the rod bolts when you check them.
