OK Denny,
I'm getting it. No decal for you on your valve cover.

http://www.brads41-46chevys.com/id15.html If it does then use it as an example and find a script/font that will satisfy you. This site has several examples that might be candidates. Brush Script MT, Tarantula Script, Harlow, Chance, True Grit, Streamline Light, and Kalligraphia EF all seemed to be possibilities for tweaking/combining their letters to get what you want.
