Not a dumb question at all.
I torque the upper bolt first, post seating, because the injector clamp slides over it and then slides downward thus locking the injector in place using the upper bolt as a reference and guide. I also used the above referenced Loctite to help keep it torqued to spec because I learned that the uppers were causing the loose injectors in this truck. Then the lower bolt is installed and torqued to spec which completes the see-saw that Rich refers to. The shoulder on the injector acts as a resting point for the "fulcrum" of the injector clamp "see-saw". If you look at the clamp, there is a slight hump.

Nicmike was gracious enough to get let borrow his. The puller tool was round and just fit into the bore. It wasn't one of the big rectangular heads that need lots of space.
