Go point Turbo, I wasn't even thinking.. to much cheeching lol.
OP did you just torque the bolts or did you take at least three bolts off then stick a pry bar or a big screw driver and see if there is a crack by moving the flex plat front and back looking for cracks.. they will crack like in Turbos pic also look for black streaking sometimes thats a tell.. look at this pic.

I just backed them out partially and torqued to spec. I didn't pry it at all but I did look for cracks and saw nothing. If it stops raining I'll get back under and wiggle her around a bit.

And as far as the engine code goes, it looks like it was a light stamp and I can't really make it out. looks like 804 ^ < (I assume this would be MX) and then I haven't a clue from there.

It definitely reads 0650. I tried taking a picture of it but just couldn't get a clear enough picture to warrant posting.

Note from DJ
Head casting number by years.
It is easy to determine what head you have. On the driver’s side, about halfway down the cylinder head between #3 & #4 fuel injector but below the valve cover clean the lip of the head with a rag or solvent if really greasy. With a good light, you can read the casting number of the head.
Head casting number by years
Casting numbers are as follows:
Year............Casting No
1987-90......2686
1991-95......7120
1996-99......0630
2000-01......0331
