Okay, after some inspection and a phone call to @bent72 (very gracious of him BTW) I have realized that the distributor was installed 180 degrees out, hence the pic from earlier. Also, something bent and I did not talk about, the harmonic is trashed, rubber is coming apart, so my pre disassembly TDC was off. Found out that my pistons are .030 over (at least the one that isn't covered in carbon), and 1 is mismatched. Also, the old timing chain was rubbing on the block.
6 is different, I can see .030 on all of them now. Makes me wonder if this is a reman from a big supplier like atk or jasper or something. The drill mark in the center of 6 might have been an attempt to even out the CR to the other 7 pistons. Could be wrong though. Also, the battery is dead in my digital caliper so cam specs gotta wait.
Hehe. If thats the worst you do
Well it freaked me out for a bitHehe. If thats the worst you do
That drill hole in what I'm assuming is #6 may cause a detonation problem. Doesn't look very radiused. Are those some scuff marks in #4?
I've pulled apart remans with four different sized pistons in them.

Definitely not worried about #4, yeah, there a some scuff marks, but nothing that I can catch a fingernail on, and this truck always ran good, even with the distributor 180 out.
Local yard had a pull-a-thon this morning, got a few things, nothing really exciting, came home and installed the new timing set. Looks like old set clearanced the block enough because the new set isn't rubbing anywhere. Still gotta get a battery for my caliper to measure my cam, there wasn't any markings on the cam to indicate something other than stock, I just want to be sure for the future TBI install.

Maybe, might just swap in the whole other engine after giving it a fresh up. That is all too far down the road to worry about it now.
Those dont look like pistons
Cam is stock.
Perfect TBI victim. Run the factory computer. Dump an O2 sensor in the pipe, few other trinkets and add a pump.
Best off road mod EVER
OMG, vindication. I AM NOT A TOTAL IDIOT. I'm preparing to reassemble this engine and spun it around a few times. The cam appears to be cut backyards on the timing chain side. I am definitely on the compression stroke, TDC #1, and the cam gear is upside down. Might not be that important to y'all, but I didn't think I was that stupid.
