Is it really necasary to have the engine
running when adjusting the valves on the
2.8L v6 (1974). Can they be adjusted cold
with compensation in the gap? ie...
instead of .014/.016, could they be set
cold at maybe .015/.017?

A neater way is to run the engine with the valve covers loose, shut it off and adjust a couple cylinders, then repeat until you do all six.

I don't know about the 74 but the later ones are adjusted when cold and not running. Might be worth checking the later specs and see if it works (it won't hurt to have them a bit out of adjustment for the time it would take to test the concept, and you can always readjust them if it doesn't work.)
