Oh and btw if you are getting headers bolt them to the heads while they are out of the truck its a life saver and will cut intsall time in half. Just dont forget to install the lifters before you put the heads on cuz somtimes its easy to get caught up in the moment. And take your time make sure you give yourself plenty of time for the install and make plans if things go bad.I love a challenge! My other vehicle is a Jeep wrangler so it's in my blood LOL! So should I get headers first? Long tubes or shortys?
