You've made my day. Not having an engine in a car here to test this, I didn't know if the tools were going to work. Very happy that they do.
Just a note for others who are going to do this. The rear jig is designed to keep the vertical sides vertical, not the top side horizontal. The vertical sides are machined accurately, whereas the horizontal sides are just the remains of the camshaft casting, and not accurately formed. In this case it has worked, as there is obviously a reasonable amount of fat in the setup that would allow for small inaccuracies. I would however recommend that people make the rear jig to reduce the risk of incorrect setup.
