Does anyone know if theres a a Chevy symbol or anything that has the purge valves cut in already...SOme people may know from the dodge "RAM"/Goat and the gas escapes through the nostrals....If not I was going to fiber glass a Lightning bolt or something just to add a nice touch to my nitrous system

You'll have to DIY that man. Most of those ram heads were made by hand buy the person who owns the vehicle. There was one small company that built them I believe and they went down a while back.
