ok, i cant decide what kit to go with. I found the kit in summit and i dont know if i should go with just the street kit or the track heat kit. My car is mostly driven on the street and goes to the track maybe 3 times a year. I am going to upgrade to the Stage 2 cam. should i get the track heat kit or just the street heat. i will be running a 150 nitrous shot on the car. what do you guys think? how about the track heat heads???
