What's the best flowing head (stock production) for these LSX's. I see a lot of people going with the 317 heads on turbo cars because of the larger chambers and they lower compression, but what if you wanna do nitrous and higher compression? Are the LQ9 the "cathedral" heads or are they the conventional port? I have been thinking about doing something with an LQ9 bottom end a good cam, good stock production heads, and go carbed with a little spray. There was a guy on ls1tech.com that went 5.70's on a 150 shot with a similar combo in a foxbody but I just cant find the thread anymore.
