Header Studs

When putting on my prochamber I replaced my studs on the drivers side with the stud kit from napa. Part number 600-1819. They come with nuts also. The difference with these studs are that the non threaded area in the center of the stud is a lot smaller. This helps the sealing issue. I heard people saying that the nuts from napa are better than the stock ones. To remove the stock studs people usually use the dubble nut method but it might not work using the stock nuts. There is a special tool to remove them. What I found to be a really easy way was to use a really big adjustable wrench. The end of the stud is rectangular and this is where I tuned it from. Now to thread the napa studs on you are going to have to use the dubble nut method.

Someone said not to use threadlock unless you are not going to swap out you exhaust again. Well I hope this helps.
