Casting in the piston should be 93L7 for 8.5 compression of 78/79, or what is the match number from old pistons in case they were changed?
Yes, the low face of piston goes to the right to face the spark plugs

I have a full new set of identical pistons and cylinders, all Euro 3.0 Liter, 95.0 mm, 9.8:1, Nikasil.

I'm trying to determine if I need to remove all these pistons from their cylinders, clean, oil, borrow/buy the ring compression tool and re-assemble. Or is it OK to lubricate, properly orient the piston, and start putting them on?
