Not what I was hoping to show you by now, but here it sits in the shop waiting for a reseal. Hope to have it back on the road I. A week. Or a month. Who knows? It’s only been 2 weeks now!

Ugh.. Not good..

Are the cylinders rotated 180 degrees? Pictures make it look like the larger portion of the fins are pointing upwards??

?? Looks like that to me too. So the bigger fins go down?

Typically yes.. Exhaust is the hotter side of the piston and cylinder.

Fyi pistons are right for sure though.

Looks like some JE pistons. Big pockets in pistons face up and long fins on cylinders go down. Looks like a 3.0 to me. Do the cylinders have the head gaskets or are you using the 3.2 cylinders w/o gaskets? Why was it torn down?

I added some pics of my brothers 83 3.0 with JE pistons and Mahle cylinders.
He has the 3.0 cylinders with the head gaskets. You can kinda see that the cylinders fins are almost the same (flat) across the top. On the bottom you can see the fins get taller as they get closer the the heads. Have your engine guy look into that before he closes it up.
