|You must remove the cam towers as them block the head bolts. If you do not have the workshop manual for this engine, you really need to get one. It is not rocket science, but it is a bit different from the other engines I have touched. You will find out things such as not mixing up the shims for the cam. The right way to replace the head and cam towers. Where the timing marks on the cam gears line up.
By the way, I used West Coast Cylinder Heads to rebuild my engine's head, as per a lot of recommendations. They were very good, knew the ins and outs of the 907 head, but were a bit slow. My advantage was that I could drive to their shop during my lunch time.
