Your best bet is to talk with a experienced camshaft design shop. I can give you a cam with less than stock lift that will bend every valve on startup, or a .750" lift camshaft that would clear just fine. Really there are so many things that go into p/v that are way more important than max lift.
Give us a call if we can help you on it, we do more LS camshafts than anyone else in the world.
