heads...cam...
Trick Flow and AFR heads are definitely top notch, but also very expensive. I would check out the Texas Speed PRC LS6 stage 2.5 ported heads. Texas Speed also has some good cam kits too, like the Torquer V.2 for example.

Personally, I think you should consider the PRC stage 2.5 LS6 head kit for nearly a grand less (spend what you save on a FAST intake manifold or other mods):

Ok, now for what cam to pick. Hard to beat the Torquer V.2 cam. If you want a mean lumpy idle lope, get it with 111 LSA.
They come assembled as a pair for around $1700
220cc intake runner & 80cc exhaust runner
2.04" intake valve & 1.57" exhaust valve
.600" dual springs
You will need to run a set of aftermarket rockers (Comp, Harland Sharp, Yella Terra, Lunati, Crane, etc).
Comp's Gold 1.72's go for $434 on Summit
Contact Ed (flowtech) or Patrick G. (http://guerragroup.com/camshaft_help.htm) and get a custom cam.
Spend another 325 (only until 02/28/10) and get your manifold and tb ported by Jeremy F.

so $1700 for heads, around $425 for rockers, $450 for a cam, $100 for push rods, $200 for gaskets, bolts, thread lock, etc, $325 for ported throttle body + manifold.... just a little over for your 3k budget but would give you one hell of a bang for the buck.
