Update on the progress. The motor has been assembled, everything apart from the head. I discovered on Thursday that there is severe wear in the valve guides and on some valve stems. All this after the head was supposedly checked out by a reputable local engineering company. I would not have known this if I hadn't stripped the head myself and had a good mechanic to check and advise. Either way, another delay and more money to throw at it. I have also chatted to some knowledgeable people about performance in the mean time. Some bits that are on order and plans include:
New set of inlet and exhaust valves
New manganese bronze valve guides
Three angle valve seats to be cut
New set of high lift rockers
Maniflow standard bore LCB
I'm now running out of things to replace on this motor, so hopefully after this round it will all be done...but I've said that before several times.
I also discovered that the spare GTS head I bought off Gumtree from a local racer a few years ago is basically scrap. I bought this before I knew much about minis. The plan was to fit it on my 1275E at the time. So I guess I was ripped off. Anyone looking for a boat anchor, speak to me!
