Hi Grumpy, have had another good look and also measured pushrod lenght, balljoint ends, tappets lenght, radious ect ect.The only thing i could find that was different was the centre pivots on the rockers, the exhaust is slightly more worn then inlet, but not enough to catch your finger nail on when feeling for a lip or divot. With the tappet if you look real close (am sorry photos dont help )a coulpe of mm's inside of the dark ring you can see a slight scoring. I put the camshaft back in with tappet and turned motor over by hand while holding pressure on tappet with pushrod, and trying to get me head in at same time, that is were i judged the pin to be hitting. There is a small depression ,the dark ring, I used a metal ruler and could see a tiny bit of sunlight under each edge, but could also do the same on the inlet tappet. Going to try an experiment, going to put all timing gear back together but backwards ie. exhaust will be inlet, inlet will be exhaust. No doubt it will be a waste of time but you just never know, stranger things have happened. Will let you know how i go.
