Project Cheap & Nasty Updated With Back Story

Ok, so I thought I was gonna have to buy some stuff. Turns out I have a good set of retainers, a set of brand new valve keepers, and what appears to be a good set of valve springs. Do any of you know what green stripe slant 6 valve springs are? I'm only going up to "about" .450 lift. I'm not opposed to buying some valve springs. I'd get the Comp 901, of course, but chit a mighty. Have yall seen how high they are now? Dangit man!
