Kohler piston ring orientation

Friend is building a kohler k301, 12hp motor. He’s wanting to know what the proper ring orientation should be. Thanks in advance
 
Gap location or ring location ?
I prefer the gaps one eighty at the wrist pin .
Oil rails offset about 30* from the ring .

This is not out of the manual . Top over wrist pin .
Second over the other side of the wrist pin
Oil half way between the first ring and the center of the rear piston face .
You can do 120* apart just don't start on the front piston thrust face or front of the block .
