recently I bought a 1969 230 Automatic, 6 cyl carburettor, with "a blown head gasket". The car had good provenance, its original delivery papers, etc.
It turned out to be an expensive exercise!. The head was actually abraded away between cylinders by combustion gases. The concensus from my mechanic and the cylinder head reconditioners was that it was not repairable, as the aluminium alloy had softened due to a previous crack and clumsy rewelding. I found other cylinder heads from wreckers, similar problems and rejection! Eventually I got one good enough to be reconditioned and it was reunited with the block. It cost me about AUD4000, twice what the car is worth!!!
The moral is:- your cylinder head may also be soft in places, and may have blown straight through again. Sorry :-(
I hope you can get the car running again.
