Where to go from here? (91 2.3)

[190Proof]

A couple months ago, I bought a 91 Ranger, 2.3 Auto.

Well, the temp gauge didn't work, and apparently I overheated at some point. I was leaving a mall, and had no power, and the loudest misfire I've ever heard. Once I was able to stop the truck from stalling and got onto the interstate, it ran fine until I got back into town.

I changed the fuel filter, plugs, and wires, thinking it may have needed a tune up. While changing the plugs, I broke the little tee on the heater hose. When I tried (a few cranks until it started) to start it, it idled like hell for a second, and the stalled out. Well, antifreeze was leaking from the broken tee, and it had that nice rainbow pearlescent look, and the was water in the tail pipe.

I just pulled the head, and the head gasket looks fine. I put a straight edge on the bottom of the head, and the doesn't seem to be any deviations across it. But in the block, there's oil floating on top of the antifreeze around the first cylinder.

Where do I need to go from here?

Head needs to be surfaced before being reinstalled, have the machine shop do a pressure test on the head at that time, it will most likely have a crack.

Heads crack between the valve seats when overheated so inspect those areas carefully.

Blocks rarely crack from overheating, actually never heard of that happening even once.
Inspecting the head gasket for a breach is hard to do unless it was a long term breach.
Look at the metal ring around each cylinder on the gasket, that's the only place a breach of your description can start.

Also, repeated or extended overheating can damage the rings. Rings are sprung steel, heat is bad for springs.
