Thanks for great info guys.

What do you mean by taper the cams?

In the first image I'm presuming it's showing the actual locking tool in place right?

Finally at what point would you put the locking tools in? Haynes seems to say you need to loosen the crankshaft bolt before locking?...
Should the engine turn okay to get the cams to a position that allows me to lock them?

What's TDC mean?
