ok a buddy and i are starting to build up ls motors for turbo. we have spare heads from an ls that we would like to build up. now the question is what valve springs and valves can we use to build it up some. My buddy is looking to get 300 hp to the ground and i am looking for something like 250 or so. i was thinking about type r springs and valves but i am not to sure what we can use. give me some insight on what we can use please! thanks guys
