No worries heath I wasn't upset or anything just explaining my way of thinking. You probably can get more power with lots of bolt on stuff but would probably loose drivability and reliability and cost a shitload I just went 2mm bigger stainless exhuast valves. Give us a yell if you find anything out about cheaper cams dotn wnat anythign wild power between 4000-7000 would be fine. Cheers andrew
