Where do I find/buy the fitting to screw into the heads once the spark plugs are removed that allows me to connect my air line to it keeping the valves closed to change valve springs with the heads on the car? I've been to every auto parts store in my town (O'Reilly, ABC, Autozone, etc.) and they look at me funny and have no idea what I'm talking about.
I don't need it today but will in a week or so ... I can order it online if someone points me where to find it.
Thanks.
Scott
