Heads or NO2??
I figure porting a set of LS6 heads cost about what a good nitrous kit and whatever else I need.
What would you guy do? Iv never been a nitrous fan but a blower or any real kinda boost is out of my reach..
Could be costly tho good kit, bottle heater, purge, would be good idea for a controller being your an m6. GL
