header bolts?

[night hawk]

Gonna install my headers next week, but i need to know what is a good bolt besides stage eight? the guy at lowes said that grade 8's would be good, but they dont come in metric, so do i get the class 12.8 bolts that ARE in metric? they only come with a hex top would that work?

Just use the bolts that come with the headers and add some lock washers. That is a cheap and easy solution.

I dont remember the size of them at the moment but I used grade 8 bolts with lock washers. You can also go to the dealer and buy 6.1 manifold bolts that have locking compound on them with the small 10mm heads to help get in tighter spots.

I really wish I kept the size written down somewhere better

The 6.1 bolts are another nice alternative. I know quite a few guys running them with great results.

The trucks have enough room to clearance the primarys that the 13mm wrench fits good and room to move around them to check. The Jeeps and cars deff need the small 10mm heads to slip in a small wrench because those are a PITA.
