Keith -

You bring up a good point, but remember that you're only applying compressed air to one cylinder at a time. If you stop after finishing one cylinder, but before starting on the next, there's no need to keep anything pressured up overnight.

However, a complete loss of air supply, which could happen unexpectedly and in the middle of working on one valve, would be a problem.

If the keepers and springs are gonna be off for an extended period, you could slip a piece of rubber hose over the keeper grooves at the top of the stem and put a vise-grip over that.

Now that I think about it, we lost a keeper for the last intake valve on that SBC, when the parts stores were all closed, and we did something just like that to ensure that the valve stayed up overnight.
