I also fitted a full copper head gasket (annealed it first) and on the first couple of runs noticed a 'damp' area on the fins where the join is, this got less ad less each run out soon there was nothing there and it's completely sealed.
Thanks! I have an iron head, so I will be looking for 5 longer bolts. Or six!!:grimacing:
In the Netherlands I can find copper spray from Motip, and copper gasket cement(VHT).
I guess they are both the same. The copper spray is advertised for screw joint, but heat resistance.
