Kill me now, please.

All eight numbers to the drivers side?
I don't think that's right.
The numbers should be on the opposite side to the squirt holes and the squirt holes should be facing the opposite bank, to oil the cylinder walls there; that is to say towards the center of the engine.Factory type pistons, have offset piston pins. This was designed to reduce/eliminate piston noise.The factory type pistons are therefore installed in such a way that they are indexed to the engine front, and also indexed to the rods. If the piston tops have big-N-little eyebrows, they also have to be indexed to particular cylinders. If the indexing was carried out properly between the pistons and rods, but then installed backwards on the crank, that could create problems in the chambers.
So just be sure the squirt holes, if you got 'em,are correctly oriented.

If the engine has been running this way for many miles, without issue,Including piston noise, I might be tempted to put it back exactly the way I found it, cuz without taking the heads off there is no way of knowing the piston orientation.Unless you have access to a boroscope.
