Head Gasket for an oval oil return ?

[Power Man]

Hello.

Im looking to run a 52.4mm bore for my loncin 125.

I need a new cylinder, the original cylinder uses a round oil return passage

Will this cylinder ,with the oval oil return work ? (aslong as i use the oval return gasket?)

Using this standard head ?

Because the new cylinder is a flat surface, no counterbore for the o ring for the return do i need to use an o ring on the oil return passage on the oval ?

Thanks in advance !

As long as all the measurements are exactly the same as the other barrel, then its all good

so if i use this gasket, I <b>ONLY</b> need to re use the oring for the stud (oil passage to head) ? i dont need an o ring for the passage return ?

Thanks in advance
