Header bolts

Hey all, a fellow list member was nice enough to give me an old header he had and I'm looking for info on the header bolts. Does anybody know the thread pitch and length needed for the Thorley?

Re: Header bolts

For the collector flange, you can use plain old 5/16" bolts, G5 or higher. For the manifold, just reuse your stock bolts.

Re: Header bolts

I don't want to use the old bolts. I'd much rather replace an old fastener especially one that's exposed to such harsh heat cycling.

I'll keep the suggestion in mind just in case I can't find the correct bolts though

Anybody have an exhaust manifold bolt they can check with a metric pitch gauge for me?
