Transfer your heads, cam, intake, fuel rails/inj, oil pan, accessories to the lq4, drill/tap 1 hole for your alternator, reluctor wheel adapter harness, new timing set, oil pump and you should be good to go.
For more power add a cam/heads/exhaust with pushrods/valvesprings etc.

Basically what letsrunum said. But I would not swap the cams, the LQ4 and 2002 LS1 had the same cams. I don`t think I would swap the heads either. Most of the LQ4`s had 317 heads. which are basically LS6 ports with a slightly larger chamber. The motor is a bolt in except possibly having to drill the one hole for the alt bracket.
Avoid the 99-00 motors as they have a longer crankshaft and poor flowing cast iron heads.
Also the newer motors (I don`t have an exact year, seems to vary by model but started in 2003) have a gray connector for the Crank position sensor.....and are 58x Avoid those because that sensor will not work with your PCM and you would have to change the reluctor wheel on the crank to get everything to play well together.

All external dimensions are identical for the lq4/LS1 (any heads/headers etc you could use on an LS1 will fit the lq4).
Pick one on the sponsors------------------------------------------------------>
I bought a lot of my stuff at SDPC as far as oil pump, gaskets etc. It's up to you where you want to get your cam from.
Here's a link for the crank reluctor adapter module:

You're best off looking in the genIII internal section and researching what is going to be good for your needs as far as heads/cam goes. There are lots of options/combos to make good power. Also consider a custom cam.

You'll need a good set of aftermarket heads to make ~450whp, depends on how much you want to spend. Trickflow or AFR if you have money to burn. In any case though I wouldn't run the 317 heads- too low of a CR.
Since you're new here I'd get familiar with all the forums on this site, because you'll have to make a lot of modifications for 450whp (gears, clutch?, torque converter?, tune, etc)
