I just read this post, because I'm still focused on the frame and gearbox rebuild right now, however, I'm intrigued - it seems (from this post), that annealing the head gasket is "required" prior to refitting, which I can understand after years of use then reusing, but why would you anneal a brand new one??
AND, on the topic of head gaskets I read a post some time back that made reference to a co. that made various thickness copper head gaskets, I've tried searching but cant find it, can somebody put me onto that please?? The reason I ask is that I rebuilt the Golden Flash engine many (many!) years ago and its been sitting ever since, and back then the only new pistons I could find were HC, which I didn't want but had no choice. Then recently I read a post about various thickness head gaskets to reduce CR, hence the question....thanks
