I've always done it that way, and never had problems. But because of some discussions on this board, and the cam grinders instructions I've read lately, I decided to re-run the valves as follows:

When the exhust valve starts to open, I set the intake.
I then ran the intake to full lift and back down until it was about to close, and set the exhaust.

Now the question:

On some of the valves, the half turn is very easy, and, right after adjustment, I can push the rocker down with my thumb. On others, the half turn is quite stiff, and I can't move the rocker with my thumb at all. Does this sound odd?
It sounds to me like some of your rockers are "pumped-up" and some are not??
