user14202: I am referring to main lines where the pawn sacrifice is accepted.  

user14079: Most reference books will give the main line as
1. e4 c5 2. d4 cxd4 3. c3 dxc3 4. Nxc3 Nc6 5.Bc4 e6 6.Nf3 d6 7.0-0 Nf6 8.Qe2 0-0 9.Rd1 e5

Followed by either 10.Be3, 10.h3, 10.Bg5, 10.a3 or even 10.b4.
They usually evaluate this 'main line' as a dynamic equality.
Repertoire books often offer other ideas for Black (with...g6, or ...Ne7, or ...Bb4, or ...a6 and ...b5, or 3..e5 or refusing the gambit right away).
