    Heads for f13 cam

    O.K. what heads would you recomend for my WS6? I have, LS6 intake, lid, ported throttle body, longtubes,3 inch all the way,and the f-13 cam.

    The car made 375 rwhp in 95* heat (I know, I just got the car and wanted to see what it really had) so maybe 385-390 with good temps. the thing I thought was kinda off was the torque which was a seemingly low 353. Does that sound right?

    What heads would I see good gains with?

    Is 410-420rwhp to optimistic of an estimate going from stock heads to good ported aftermarket units?
