True. However, if the rocker arms are cranked down too tight, the motor won't fire. And since he had the heads off and had to reset all of them, there's a good possibility the lifters bled down in the meantime and he overtightened them. When we built my 305 eons ago we did the same thing, and it wouldn't fire worth a damn - sounded like it wanted to, but just couldn't. Once we loosened everything up 1/2 turn, the motor came to life and we re-adjusted the rocker arms.
I agree though, he should check his firing order and dizzy first before tearing the valve covers off again.
