Wow... I just read my post and realized it was all wrong... Sorry about that guys.. 
To make good power with these engines, you don't need fancy heads, special intake manifolds headers and whatever was listed above. It helps but it's not needed. You can make 750 fwhp with a stock 6.0 (LQ4) the right cam and turbo, if the tune is right.
