It's unlikely you can change the cam to one which will gain any significant improvement without a change in ECM calibration and maybe even an injector change.

That said, a change to the AFR LS1 head, the cam AFR recommends to go with it, late LS6 valves and springs, the 02-04 LS6 exhaust manifolds and cats will have you at 450hp.

thanks for your message.as first stage I would like to go for the cam+valves and springs: I target 25/30 Hp increase.....heads could follow.
Manifold intake :I was thinking to go for Fast but are the money justify ?
ECM:in Italy not too many expert to play with,I prefer not to take the risk.
Could You kindly specify AFR
thanks and regards

If you are going to replace the valves and springs, the heads are already off the engine block. Why double your work (by removing and replacing the heads to replace the valves and springs the first time and then a second R&R operation to replace the heads)? I doubt if anything that canges the fuel injection timing (of which a cam change is almost certain to do) will not need an ECM re-program.
