The machine shop I used pressed the Omega pistons on the conrods with two pistons facing one way and two the other way. Actually, it was my fault for not specifying but does it matter which way they face. They appear to be symmetrical and the shop assured me that it is not an issue but I am not sure I trust their word since it is an American shop that rarely sees anything besides GM and Ford. Thank you!

With those is ain’t an issue. But some do have offset dishes.

Maybe worth a call to MED, as they may have a T on the inside on the skirt indicating the thrust surface. I'm not too familiar with Omega forged pistons.
