I just got a 1mm copper headgasket from Dr Atv for my gpx with akunar 140 lifan head. Is the oil return hole in the gasket supposed to be an oval shape rather than round? and i assume no gasket goes in that hole either right? i oredered the gasket for the lifan/zongshen. i lined it up with the engine studs and that is correct. thanks

mine was oval and i didn't use anything but a thin layer of copper permatex on both sides of the gasket-per hack

the honda uses a black oring on the top and bottom of that passage

i kinda figured thats how it went. I feel like an idiot asking all these questions. i have built numerous honda motors, but these gpx motors are a little different. Thanks for the help
