Ok so it's definitely head gasket...
Discussion
Got the heads off tonight ready for skimming. Having chased overheating issues all year thus far, and it having ruined 2014's Cerbera use, I'm almost relieved to see the state of these head gaskets. The engine has covered 35k, and as you can see, there's not much left of these.
One thing we noticed is that the bores of the pistons had a bead of silicon around them. Is this normal? It was coming away so I removed it.
Regular progress updates will be provided for the nosier of you.

Too late for copper gaskets, Racing Green delivered some standard ones a few weeks back. The heads will be going off for skimming and cleaning over the next week or so. The intention was just to clean the block faces and studs up with some emery paper ready for the refurbished heads, but I will consider replacing studs etc while everything is apart.
Simon, I have only just seen this. I didn't go for copper gaskets in the end; the heads unfortunately hadn't been skimmed flat when I had them done, which Track V Road discovered when they collected the car. There was also still some corrosion left on the head faces so had to have them done again, more aggressively than would be ideal. I have had a spacer made with 3mm cometic gaskets to keep the compression ratio within safe tolerances. The engine is going back together as we speak and the car should be back in a couple of weeks ready for taxing in March. It will be nice to be able to kiss goodbye to the overheating issues.
