X pipe too.

So larger headers will net me a nice gain. I'll wait to do an X pipe for when I do my watts link. I was told the heads were restricting the setup. I guess it's the intake and exhaust. Does it matter what brand headers I get? My minimum requirement is ceramic coated or stainless steel. Other than that I've been pretty easy going with brand selection. Had no idea headers could be so restrictive.

I run pace setter headers into a kooks true dual. I want to say the ARH are probably the absolute best.

Your heads are fine. Stock ls6 heads can approach 500~whp with supporting mods. You need some of these other changes around them....you will see the most benefit from the changes mentioned. Realistically you could pick up another 50~whp by dotting your i's and crossing your t's.

Ported fast, larger headers, light clutch, ewp, crank scraper, bigger maf, x pipe exhaust, roller rockers

Kooks, arh are both top of the line headers. There may be others less expensive alternatives. Do some research on them but 1 7/8" is minimum.

Some like a stepped header....but they are usually more costly.
