Does anyone know where to order or exactly what size would work with these? I know a standard header bolt won't work. Anyone have a part number handy?

I bought this set from Hardin 420-906211.

why not measure the bolt holes,add 1/2" and order from macmaster-carr.get some nice stainless bolts and washers.

We use SS studs on our Custom Marine exhaust. Studs are easier than fighting with bolts. ARP is an option or http://www.kelkoproducts.com/stud-bolts.html.

I do the same on my stellings headers. well, four studs per side, since the way the pipes sweep, I still need bolts on the other half. But, when installing those heavy old headers, the studs are nice!

With Gil's you'll never be able to get the center ones out using studs. I get stainless socket head cap screws from a local fastener supply. About $12 for 16 long, 16 short and 32 washers.

yup,,I use 2 studs/ manifold on the short bolt holes,even on my set up,which is fairly tight in the center,I can install the manifolds.no more blown out/ripped exhaust gaskets anymore.
