It doesn't need to be a 502. All of the bridged rocker heads back to about 1974 are basically the same. 73 and earlier heads used individual rockers and screw in studs like a Chevy. My guess is...

I'm not seeing anything that looks like the head gasket failed. There may be a crack by the lower bolt hole in the last couple of pictures. It doesn't look like it made it to the water jacket...
That's where the heads usually crack, either 12 or 13 (the end short bolts). There shouldn't be coolant on any of the bolts, all should be blind holes. I would check that #14 bolt hole to be sure...
If you could find someone with a coolant system pressure tester I suppose you could attach that and pressurize the coolant system and look for leaks. It may only leak when the engine is warm though....
Hate to say it, but it's pretty common for AMC heads to crack at the bottom corners. There was a sharp corner left in the casting and they stress crack. Chances are that it cracked when you torqued...
