Ive been thinking about building the head of my gsr before i end up going turbo. I was looking around and i know that overlap is not something you want when you are running a turbo. My friend said that you could run CTR cams and you would be able to tune out the overlap once you turbo. If this is true couldnt you tune out the overlap with any cam? I was looking at crower and skunk 2 stage 2's and just wondering if it would be an alright idea to build my head then have them tuned again once im boosted or if that is a recipe for disaster. I just want something to give me a little more power and help in the long run as well. Any responses would be much appreciated. Or ideas thoughts. Anything pretty much.....
