88 MJ Head Gasket

My 88 MJ is just about to blow the head and I'm trying to catch it before it gets bad. Didn't want to start this morning, once it finally did I saw smoke, popped the hood, antifreeze was everywhere, checked the dip, just the tip of it was muddy. I knew it had been leaking a little but its never really affected the truck while I was driving. Its been running alot rougher lately and louder too, which makes sense.

Should I just replace the head or with it not being bad, can I get away with one of those head gasket fixes at the parts store? It just figures that it breaks and now its snowing.

those head gasket fixes from the parts store don't do crap. just replace the head the right way to properly fix the issue
