Cam only is the LSX standard. No'one cams a LSX and keeps the stock shit exhaust, stock TB, stock air induction setup unless thier a freaking retard. So when you hear cam ONLY, rest assure that he has the normal bolt ons as well. Yes to be "correct" they should say cam AND boltons. Same would go for heads n cam...once again, they probably have the standard boltons but with ported heads & after market cam.
