Ok, spoke to Kyle at Mahle Tech Support(they own Perfect Circle) after searching online for end gap specs(with no luck). Kyle had to go to 2 places in his database to get files, I asked he email them to me. Specs are quite wide(IMO) 0.010"- 0.047" for 2 Compression rings, and oil rails are 0.015"-0.055". So compression are good and I will check the oilers.
