Any suggstion what type of bolts to use in this area or what not to use? I was able to come up with some copper nuts now I'd like to find the correct bolts for the exhaust flange.

The exhaust is stainless steel.

I've got stainless headers and use the stock hardware. Works great.

If you are looking for an upgrade lookup ARP fasteners.

Give a call to Maryland Metrics (http://mdmetric.com/). The salesmen there are very knowledgeable about the type of nuts and bolts that are best suited for various applications. They have every type of metric fastener you can imagine, and some that you can't. B)

I replaced my exhaust flange bolts with studs and a special type of brass nuts and lock washers. Eliminates the problem of breaking off the stock bolts which eventually rust solid into the cylinder head.

Regards, Maurice.
