  • What size headers bolts do I need?

    I ordered some pacesetter headers and they do not come with the bolts so I need to know what size bolts I need and where I can purchase them.

      they didnt come with them? mine did and so did alot of other peoples....anyways, the header to y-pipe is 1/4 in" and your going to need a full thread bolt around 3"s long. nuts and washers to match.

        LS1 exhaust manifold bolts will work, they are easier to install to b/c of their 10mm head

              I dont know about the LS1 bolts, but I ordered a set of the Stage 8 locking SBC bolts and they would not work. The size is correct, but the threading was different.

                  Yes, the LS1 exhaust manifold bolts will work fine. They are what I have been using for years and love em.
