    I found another broken exhaust manifold bolt. This makes three. Now I am considering pulling the manifolds, replacing the bolts and installing headers. I have searched the forum and all the header threads are old. Anyone have headers on their Escalades? Good or bad experiences? What brand? Long tube or short tube? Louder? Performance gain?

    Re: Headers?

    Check out this article from Hot Rod Magazine. http://www.hotrod.com/techarticles/e...s_small_block/

    I came across this article awhile back while researching the LQ9 engine we have in our trucks. Long tube headers give a pretty decent boost. They did the build up in stages with headers on a stock engine and tune as a starting point. It looks pretty impressive to me.

    Re: Headers?

    Are there any problems with changing spark plugs with long tube?
