Well guys, I blew a spark plug out of my passenger side head, and am ready to upgrade the heads anyways. I need a good streetable set up, while making good power on a stock bottom end for now. I currently have full bolt-ons minus headers and a nx 100 shot. I was leaning toward a stage 1 head and maybe a set of stage 2 cams?? Any suggestions on companies to go with?? Any help would be awesome guys.
