Well it hought i had better update this as its been quite a while, well since i reaulit the gearbox i have had to take the engine back out and rebuild that with another block and head, as it had over heating issues i couldnt get to the bottom off. I managed to get hold of a ported and polished head and put new double valve springs in it, finally got it running again today after a year, no just got to get it bolted together and book it in with Jano and get it set up ready for the road
