heads depending on which ones you get will help out a lot search for cams and you will find that a lot of those can give you an increase of over 35 rwhp like the zo6 cam for instance but that will drop your low end a tad for a huge top end pull increase and everybody seems to like TOG headers but i like ASM headers personally (even though i could not afford then ) a nitrouse kit will prolly get you there alone if you are not afraid to give that a shot haha do not forget about my favorite my TCISF3000 although you will also hear a ton of good stuff about vigilante and yank because that along with some gears will easily take off a half second in the quarter read some posts on that and some gears i think i am going to spend maybe 4k and am hoping for under a 13 quarter but i am also getting all the work done for free good luck and like i said earlier look >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
for good stuff i like tbyrne and arizona speed and marine (ASM)

Some of your top mods should be:
-Gears (4.10s are a good choice b/c of the OD in the tranny)
-Converter maybe a shift kit too
-LT headers
-decent catback
-custom (or dyno) tune
-nitrous (if you don't want to go inside the engine)
Relatively cheap stuff that will get you moving quick in a hurry.
The big stuff like blowers, heads, cams, etc. will really wake the truck up, but cost a **** load.

I don't see a 5.3 putting out 375 RWHP NA and still be driveable (in a truck), it could be done, fully ported heads, high compression, and a huge cam, but you'd have to spin it to around 7000rpm.
6.0L 400rwhp is easily done.

Chevy High Performance put stage II LS6 Patroit heads and cam on an LS1 and made 506 HP and 459 lb/ft, this is at the motor.
Engine Spec were
5.7L
cam - Patriot 226/226 at 0.050 .585/.585 lift on a 112 LSA
Compression - 9.5:1
Heads - Stage II Patroit LS6
intake - LS6 and FAST intake tested
Stock 428hp at 5900 427ft/lbs at 5000rpm
Heads, cam, LS6 intake 506hp at 6400 459ft/lbs at 5000rpm
Added Fast intake 522 at 6600 466ft/lbs at 5100rpm
I figure - 25% should give rwhp. they are not running any accessories.
Add more displacement, compression, maybe a little more cam, should be well over 400rwhp with a 6.0L.

If you're looking for natural aspirated power, check into Intake, Exhaust, heads and a custom cam. I'm pretty sure you will lay down 350 at the wheels with a 5.3. And i forgot to add a custom tune in there.
