ring placement?
As long as they are in the right groove and facing the right direction (numbers facing top of piston on top and second,oil control is not directional).Radial location is not important.The cross hatch in the cylinders rotates the rings in the piston grooves.This allows even ring wear.The old tale of the grooves lining up and causing blowby is false.In the first place pressure is not a "line of site" kind of thing.The fact that they all line up or are 120 degrees apart,doesn't make any difference to pressure.When I assemble engines I line up the top ring towards the wrist pin on one side and the second ring opposite that.Just a habit.If you were to disassemble the engine after it has been run they will not be in that location any longer.

thats funny, because the Helms manual says not to place any piston gaps in the wrist pin location or on the thrust locations...
So let say you are looking at the piston from the top, like a clock... your wrist pin runs from 12 o clock, to 6 oclock, and the thrust location is at 3 and 9 oclock... you would place one gap between 10 and 11 oclock, the second ring gap between 7 and 8 oclock, and the oil gaps evenly spread between 3 and 6 ( like one between 6 and 5, one between 5 and 4, and one between 4 and 3....
thats what the helm's says...
