cylinder heads

[Holden08]

Hi G8's

I have CR8 2008 GM 6.0 Ls2 engine with six-speed manual gearbox
I'am to go for some modifications and they're as follows
Longtube headers, xforce exhaust systems, vararam intake system, Fast LSXR 102mm Intake manifold with 92mm throttle body , 3.5" g force aluminum light driveshaft and double plates clutch includes Flywheel disc !

I have alread made my mind with all the parts and their brands but I only have a doubt about the cylinder heads , pls advice what's the best brand or which cylinder heads will give my car good performance ? will I need to replace my stock injectors and ignition spark plug wires ?

Heads are darn good stock.... there is a guy with about what you have and he installed ARF 230 V2 heads --- milled to 65 cc nd some other proting on intake and they jumped from 397 to 504 rwhp.... see GRRRR8 forums and "partick g"
