motor motor part four

[Jeff Gruber <jgruber@demainsoft.com>]

I just received my order of three studs to hold the manifold to the 
cylinder head.

One of the studs is steel and the other two look to be made of copper.

Are they copper or just treated with something that makes them look copper?

Is there an advantage to the "copper" or the steel or vice versa?

Thanks
