I have been running my early gen Saitos, (without the quiet cam profile) on between one to two thou clearance. Easy to check as I cut a strip from a shim each thickness and ink marked them for thickness. The one thou should fit and slide with the valve closed and the two thou will bind. Quick and dirty and works fine.

If everything I learned means anything, you need some clearance as you are checking cold. When the engine is at temp that clearance can close up. If set too tight cold you run the risk of incomplete valve closure, especially on the exhaust. Short life expectancy for the valve face and/or seat.

Hobbsy, we woke to the same thing this morning. Had to clean off the car to go to work. Remote start is a must here. As for your neighbor, another argument would be to ask her if she cooks with alcohol. If so no more wasteful than powering a Saito.
