From these pics, it looks as though the two on the left are recessed in the center portion and are 8.8:1 while the two on the right are raised making them 9.0:1

If this isn't the case throw some more revealing pics up. Otherwise I'd say you don't have a matched set here.

If indeed 8.8:1 they are a great item for stock piston builds. I've got some on the shelf waiting for the rebuild.

yep, it definitely looks like they're not the same ones.
also I hope no one is cazy enough to re-use rings, and re-use stock rods in a built motor.

thanks for this info, you are 100% correct on this.
i dunno how this happened because i pulled these out of a block myself....
but seems like i have 2 different set of pistons.

going to do some research on this, thank you!
