Dude, I had exactly the same thing happen to me!
Thought it was head gasket, tore down the motor, and sent the head to a machine shop to have it checked for cracks.
Seriously, this guy did an amazing jop. He checked the head surface, replaced the valve guide seals, cleaned it up and made it look brand new.
But whatever testing he did for cracks didnt work
After reinstalling and finding that I still had coolant steaming out the exhaust, I did my own test and confirmed that the head was cracked.
Anyway, its your call.
Its more work and time spent as a lawn ornament but I felt it was worth it.
And its easier to sell a vehicle thats in good running condition than one that isnt.
I got a good used replacment head shipped from england for under $600.
So, if you decide to stick with it, contact VMspecialists.
Just be advised, you gotta be patient with them. Not only are they in a differnet country (thankfully english speaking) but their working hours are different.
In the end, I was very pleased.
