Default Been a while but I'm back!

Joined the Army and just finished all of my training so I'm back, at least for now? Car just hit 28,000 miles and runs better then new! Any how.. I'm ready to do some more mods. Done the CAI air intake, custom 3" exhaust and down pipe and have added the carbon fiber Inferno hood. Oh, and have also been dyno tuned but that was just with the down pipe. Car seems to speed up for a split second after letting off of the gas at full throttle in 3rd so I think I'm too lean again. More tuning will have to be done.
Just ordered R1 concepts cross drilled and slotted rotors with Hawk pads. So brakes will be done too. STOCK SUCKS! already worn out and warped.
Should I do Rockers and springs or a ported Intake?

Just Ordered LS6 valve springs and the Crane 1.8 roller rocker kit with push rods, guide plates and rockers with adjusting nuts. I will be using the Tim tool with the air hose to hold the valve's open. I also ordered some STB's with brackets. I will contact Jeremy tomorrow about intake porting. Hoping for 300hp at the wheels
