I am leaning more toward the battery as a starting point as the relay shouldn't be showing under 12v, as far as I know.

Hi Zach,
Some of the replies are from owners in warmer climes! In Canada, if I leave my 300D outdoors overnight in winter, it is always hard to start below a certain temperature even with the block heater on. Batteries don't like the cold weather either!
I used to use my 300D as my daily driver. I kept it in an unheated garage overnight usually without block heater. It would sit outdoors at work for 8 hours during the day without a block heater in all Canadian winter conditions. I only once had to call for help!
You have done most of what is needed:
- valves properly adjusted (and good compression)
- New glow plugs
- block heater (make sure it is working!)
I would first jump from a battery on one of your other cars. That should ensure full voltage. If that solves problem, a new battery will no doubt be needed. Nothing like a good battery in a 300D!
I made my own reamer but didn't find much build up. But reaming wouldn't do any harm if you are going to pull the injectors. I wouldn't if they test out - It's a bit of a pain getting by those injector tubes!
If one new glow plug is bad - I would wonder why? Perhaps just a bad connection at plug or at relay? Have you cleaned relay contacts and checked connections? (I have not read complete thread)
Again haven't read complete thread, but some cheap aftermarket glow plugs are apparently prone to failure even when new.
I have not tried this solution, but it looks interesting:
