no no no im not saying anything about there not being good info in this thread...i just wanted to see other threads of guys who used them and with combination, what size valves, flow #s, etc....wanted to immerse myself in more info about them that is all, since i know nothing about them...the guy at the show kinda sounded like a goof when he told me to my face that x heads are garbage on my 340, but i dont know anything about 302/308 heads so thats why im asking here...that is all...didnt think i would get in trouble for asking
