what to do to get more hp
Talk to Patrick G about a custom spec'd cam.
AFR 215 (milled for min. of 11:1 compression)
Fast 92mm
American Racing headers
4" Mufflex system or 3" Duals
150 TNT F2 kit w/ Nano
The real question is do you want to keep the stock bottom end or do you want to open it up for forged/stroked parts?
If you do i would consider a 408 build and jump up to
11-11.5:1 compression
CNC L92 heads
102mm intake (possibly ported)
ARH big primary headers
custom cam like before

I know a guy who will ship you a set of like new LS3 heads w/ rockers and intake manifold with fuel rail and injectors for 1075 shipped.
That paired with a custom cam will yeild ~470rwhp.

The only thing with the L92 heads on a stock LQ9 is the huge valves limit cam size, and the pistons need to be flycut for anything serious. (assuming you keep the stock bottom end)

Verdad Gallardo I imagine with a mild NA cam, that won't be necessary. I would get a cam custom ground for your set up, then measure the PTV clearance with the cam installed. Having to fly cut is not the end of the world.
This is the cam I was going to go with before I changed my direction to FI:
223/231 .610/.617 113LSA +4 advance using Comp LSL lobes
Here is the link to a thread by Pat G detailing the results with that cam (dynograph is posted):

Great looking power curve! You could vary the cam a little to pick up some more top end power while giving up a little low end torque.

Damn those are good numbers. I would have milled them, ported the MAF/intake, went to a 100mm lid, and used LT's with 3" catted Y-pipe and a 4" mufflex system. That would put you EASILY in the upper 400's. (~475-485)
I wanna see someone break 500hp with one of these combos. Damn that got me drooling over building the 6.0 i have laying in the garage.
Imagine all the people you would **** off with such a basic low dollar build.

U have nothing on me homie, I got like 3 tornados and an electric supercharger taped up and stuffed in the intake, top that homie 
you don't want to see me creep up on you with my 24" yo
