Several 282 heads have been for sale on the Club Rambler Mexico Facebook page. Just find one that is not cracked, get it redone and go with that. They are cheap.

I got my head back from reducing the height to increase compression ratio and the port out.

I am finally able to see and take pictures of the crack. Starting at one of the cooling ducts.

I'll have my mechanic check it out and see what can be done about it. I've confirmed this crack was already there before I had the head ported and reduced in height.

The mechanic that worked on it told me that with just the head gasket I'll be fine without any risk of leaks, but if I can have it fixed right away I'd rather do that now that the head is off the car.

Yes this can be fixed.
Obvious, looks to propagate from the stud hole through the water jacket and move between the center.

I would tend towards brazing this instead of welding. two reasons 1) welding will likely propagate the crack further and 2) warpage in the center of the head.

Find the end of the crack and shallow drill a 3/16" hole, then taper grind the crack out to the stud, preheat the head to 330 to 400°F and then braze from the drilled hole out to the stud.

Finish with files and check head for flat or better, mill 0.010" off.

This is what I would do, others may have other/better options.
