I'm looking at getting stg 2 heads from patriot performance. I was wondering if anyones running these heads, what kind of gains I'm looking at, and maybe even some convincing to try a different brand. Even if someone could post a link to a thread thats related to my question, that'd be great. (I'm only researching for the time being, got a bit of work before I get to actually build my engine up)
