I still think if you have cooked it the rings may well be stuffed. Just make sure its not rings before putting the head back on, otherwise you'll be repeating the process. With the kms on it it may be worthwhile popping the pistons out and giving it a freshen up, providing the bores are ok and measure up correctly. With new rings in it then it will take a turbo. 
A freshen up isn't that hard to do and you already have the head off. Of course if you are certian it is the head and only the head then I would leave it.
Sorry I am not trying to confuse you, just passing on the crap I have been thru before.

Not Co2, carbondioxide

Make sure when removing the cyl head, that you loosen bolts in the reverse order of tightening sequence to avoid warping. The head gasket comes in 3 different thicknesses--no1 being the thinest with no3 the thickest. The number is stamped on top of the gasket just adjacent to the alternator. If in doubt, fit a number 3 particularly if your having the head re-surfaced. The cylinder head is very heavy and when replacing, be careful not to allow the locating dowles to scratch the cyl head mating surface.

Just some other shots of water pump cavitation and electrolysis where aluminium front timing cover joins steel front engine plate. This is what the grounding strap from themostat housing to body is supposed to prevent... It would be worthwhile checking these parts while youve got the cyl head off.

Roughly about 6 months ago finished a complete re-build-have done about 20,000km's since. Cant find the receipt, but i can tell you that the Nissan part# is 11044-06J02. For a grade 3 gasket. Make sure shop only takes what they need off the cyl head when decking. Check for cracks in precombustion chambers and between exhaust and inlet valves..

At least you got to drive yours.....When I rebuilt my SD33T in the MK last year it took me over a couple weeks after work and chit to pull it apart and get all the parts checked and then put back together again.
At midnight on a Saturday I was there having completed the install and thought what the hell lets at least fill it with water before I go to bed.
Got the hose out and filled the bugger ensuring I didn't spill any water to hide and leaks......Guess what it leaked worse than before I had rebuilt everything. If you know the what an MK is like you will appreciate what a pain in the arse it was to have to pull everything apart again. You have to remove aircon and brackets and pwr steer and filters and heaps of other chit just to be able to pull the head off.
When it was finally pulled apart I looked at the head gasket and guess what it had a seal missing from one of the water jackets........One very nasty phone call later I had another gasket in hand, with the vision of another day to install.
Don't be put off just think of all the days of 4x4ing your going to enjoy with it...........And also remember sometimes it is just not worth the saving to use non-genuine parts.........

a faulty radiator cap will lower the system pressure and thus cause oiverheating.
just my 2c anyways
