Bought some NEW P&Cs on Ebay and...

[Bullet Bob]

I got this new set of Alusil pistons and cylinders on Ebay and they were delivered today. Well, I unpacked them and they do look new but they aren't a matched set. I brought them up to the shop and began to take some measurements and everything looks good and I do believe they are indeed new but there was one cylinder from a different height group (group 6 instead of 5) and it measured to be .0008" taller than the rest. I also had two heavy pistons. The pistons weighed at:

656.5
654.1
653.8
659.8
653.4
659.7

The ring to land clearance was .07mm on all of them as well. So any thoughts? Are these usable as-is? It seems like .001" could easily be sanded off the cylinder and the heavy pistons could be installed on opposing cylinders to balance each other. Any other measurements I should be looking at? Comments would be appreciated.

Also, I got 190k miles from my previous set of Alusil pistons so it doesn't bother me to throw another set in there. They were also a pretty good discount over new Mahle's.

Probably get better answers in the engine building forum. You will want to balance the pistons, rods, wrist pins, rings, etc in complete sets to get the best balance.
