Recently I've been looking around for a new heads/cam pack for my 2002 WS6. AFR heads seem to be the top pick but they're around $2500 new, which is damn expensive. Wondering if anybody has any good performance heads/cam out there that they're selling. Looking for a cam around 550-590 lift probably. Duration between 225-230 or so. 112 angle would be better than 114 but i'm open to whatever there is. Thanks!
