Ok guys, i having trouble with my parts list. I am going to get a trick flow track heat intake and 70 mm throttle body here soon. Im haveing trouble figuring out what gaskets i need. I need the lower intake to heads and block gasket. I also need the throttle body gasket and the two sensors on the throttle body gaskets. I dont know which ones. Also what exactly does the timing light do. Is it just a light to see where the marks are or what, Please explain that to me.
