Default Gilson Valve Help

Doing valves on a 1 3/4 hp Gilson Johnny-on-the-Spot hopper cooled engine.
Existing intake valve is 4 1/4" overall & extends 3/4" above guide with valve closed. With keeper & pin installed valve will open only about 1/16". My options are to make a new valve or trim height of valve guide. New valve preferred but what overall length?
The exhaust valve is 5 1/4" O.A. & extends 1 3/4" above guide with valve closed. This appears to be close to correct length. It appears from photos posted on Denis Rouleau's site that valves should be different lengths.
I'd like to know original dimensions for intake & exhaust valves and just how much intake valve should open before keeper hits the guide.
Thanks Harry
