I'd personally run the Brad Penn 20w50 or the Hogsnot 20w50. Both have excelent high pressure additive pacakges and have the proper vicosity to support clearances that large. If you want hogsnot oil by the case drop me a line. I can also occassionally get Brad Penn by the case to but its much harder to get.
