In a couple weeks I'm installing Texas speed stainless long tubes on my 2000 silverado 5.3 and was wondering what header bolts to use? Could I use some from acdelco or something like that? It's a Midwest truck and I don't think ill be able to reuse they are pretty rusty and I wanna use something kinda nice as well, but let me kno what you guys think and thanks for the help!

 

It doesn't come with header bolts? I know a few people running stage 8 locking header bolts and no complaints. Just becareful taking the old ones off.. They like to break.

 

You can get a set from Summit as well.

 

No they didn't come with any that I could find, I looked in every box and I didn't see any bolts and I will check out summit

 

What size are those bolts that are on the manifolds?

 

eBay has header studs. I'm running them with my turbo manifold

 

M8 x 1.25, maximum drill depth is 16mm so add the thickness of your flange and that should give you an idea of how long the bolt needs to be..

Sweet!!! You guys rock this helps a lot, if anyone has more info have at it!!

 

I just ordered some Stainless ARP Header bolts from Summit Racing...$60. Going to use them with my ARH header install hopefully this weekend, if they get here by then.

 

Check out Percy's split lock bolts. Used them several times. Look great and wont back out.
