Evening all. So yet another evening on the car but finally some progress. Installed the 2 sets of head shims and the first 4 rocker arms. The wipe pattern is now within 0.52mm of the center. The valve side reading 0.85mm and the pivot side at 1.37mm which I think is pretty good.
In other news the previous owner obviously didn't like using a torque wrench as 3 of the threads had helicoils in which tore apart when I tried to torque the bolts. So these where taken out, the threads cleaned and reground and new helicoils dropped in which, luckily,a neighbour who stopped to have a chat happened to have from a Ducati rebuild.
Not looking forward to what else I will find now but hopefully upwards from here.
