1: 182 psi
2: <30 psi
3: 180 psi
4: <30 psi
5: 180 psi
6: 168 psi
From sticking my crappy bore scope down there I can’t tell anything obviously wrong with pistons 2 and 4.

Doesn't really matter at this point. Your compression losses are either: due to warped valves and they don't seal and air either goes to the intake or exhaust side. Or, breaks in the head gasket where air can exit into the coolant system.
In order to determine which, you need to get a leak-down testing tool. Compressed air at 10-20 lbs is sent to your cylinder while at TDC and if you see bubbling in the coolant tank that's a failed head gasket. If all the air rushes through exhaust or intake, your engine head valves no good.
If just the head gasket, go ahead and replace it.
If bad valves, Buy a known good used engine from wrecker, take the head off, install onto your existing block. Run compression test again, more likely than not going to solve the issue the most inexpensive and quick solution.
