Regardless, the factory LR manifold isn't exactly a slouch and we've got about 285 cfm out of a set of C3 LR heads, up from about 240 cfm.
A head and cam change would really turn that engine on. If you like factory iron, your heads can be worked. Otherwise it may be more cost effective to go with a set of edelbrocks. Even out of the box edels with a nice valve job and backcut valves would be a noticeable improvement.

Listen to this advice. Your budget will govern what you do. Well, mine never does but that's a different subject.
