That's a relief Bryan,  I'm  not sure if I want to find any other issues that answer my problems or whether a clean bill of health would be good.  Either way I'll be fixing a head gasket leak so it's all positive!

Oddjob:
Has some pitting on number 3 inlet lobe, the journals are a little tramlined as well, depends a lot on how the journals are underneath on the head TBH. Post a pic of the rocker arms and the camcover as well, but before you do anything remove the tacho drive, CAREFULLY. It's breaks for fun, right where it meets the top of the camcover, a lot of the time only the bolt is holding it together. Push from underneath rather than try to lever it out. If it's intact store it carefully. They are expensive to replace and VERY easy to break if left in the cover.

The cam can be re-profiled if there is more pitting on the lobes.

The dreaded instant gasket has made an appearance, haven't seen that stuff for a long while now. Very common in the 80s.

Dont remember seeing where you are located apart from uk, which whilst smaller than us still covers a big area
