Ok ok ok…
Time to get it together already.
S1 XJ6 4.2
I’ve noticed these strange deep gouged marks just behind #1 combustion chamber on cylinder head.
Very weird. I can’t imagine what caused them.
As you note, they are within combustion area of cylinder head gasket.
The removal of head did require persuasion and patience, however I am experienced and used bottle jacks and pieces of wood only.
Always very aware and careful of head surface and during storage.
I would chalk it up to some weirdness or failing on my part, however I happen to have another original S1 XJ 4.2 head which came with another car I’ve since sold which has same marks/location which makes this very bizarre and curious.
The gouges are deeper on other.

There were no head gasket issues, and very fortunately, despite the deterioration of coolant causing some serious corrosion concerns, miraculously the head and block passages/surfaces are all ok.
Upon cleaning and hoping surface requires no machining, considering attempting some brazing and gentle filing.
PS: Checking to make certain images uploaded, note how the combustion chamber edges are out of round at the location of those gouges…weird.
