Also worth doing IMO, is to remove the timing chain cover.

I then cut a nice circular hole centrally in the main section over the cam vernier wheels, and made a circular cover plate.

This means you can fit it all together, and adjust the cam timing without having to dismantle it all again.

You just remove the new circular cover, adjust and replace.

I even bought some gasket paper and made a nice gasket to seal it up, and tapped the holes for the cover into the main cover with 6 screws...
