Default 99 C5 LS1 mods?

Hey guys,
Im looking to make more hp out of my stock ls1 engine, wanted to know what are the best mods to do so without any major work?
I was thinking about porting my heads, a cam and a full exhaust with long tube headers?
Let me know your opinions!
Thanks Guys

That's what I did (except I bought heads) and I am very happy. Super charger is also a possibility.

I gotta say, in my mind heads would pretty much fall under the "major work" category. Basically anything cracking into the motor would be major in my mind. Even a cam install is a decently difficult procedure.

I'd start with a Vararam, LS6 intake manifold, long tubes into a full catback, and get tuned. So far the biggest improvement that I've done has been the 4.10 gears as far as seat of the pants goes.

Exactly what I did, I made 420hp at the wheels with a mild port and the stock intake manifold. I will be installing either a Fast or Street Warrior manifold this winter along with a full port and polish on the heads.

I almost forgot, do you have an auto or a stick? This will determine what the best mods are.
