Thank you for the tips. I found a decently priced head check in town and got it resurfaced/cleaned etc. Got it running and compression is great on all cylinders! I leave this as a warning to other frugal (or cheap) home mechanics like myself. Just spend the money and have the professional look at it!
Currently I'm struggling with heavy smog while running, all plugs are getting equally blackened so I don't think it's one injector sticking open. Fuel pressure is 35 psi at idle. I did a lot of poking and prodding and finally noticed a cracked exhuast manifold on cylidner #4. Assuming that's tricking the O2 sensor into running rich. On the hunt for a new one or a fix and I'll update once it's replaced.
