i have the same headers and pulling spark plugs is a little time consuming, the driver side is the easiest, you can just use a socket, but the passenger side is a bitch cause of all the shit in the way that you have to take off to reach the spark plugs and a few of them are hard cause ya really cant get a socket in there to reach them, i was able to jimmy a wrench in there to loosen them up and finish takeing them out with my fingers, but i quess it all really depends
