    A note to old forum members...
    I receive numerous requests from people who can no longer log in because their accounts were deleted. As mentioned in the forum FAQ, user accounts are deleted if you haven't logged in for the past 6 months. If you can't log in, then create a new forum account. If you don't get an error message, then check your email account for an activation message. If you get a message stating that the email address is already in use, then your account still exists so follow the instructions in the forum FAQ for resetting your password.

    Have you forgotten your password or have a new email address? Then read the forum FAQ for details on how to reset it.

    Any email requests for "can't log in anymore" problems or "lost my password" problems will be deleted. Read the forum FAQ and follow the instructions there - that's what we have one for...

  • Returning Visitors

    If you are a returning visitor who never received your confirmation email, then odds are your email provider is blockinig emails from our server. The only thing that can be done to get around this is you will have to try creating another forum account using an email address from another domain.

    If you are a returning visitor to the forum and can't log in using your old forum name and password but used to be able to then chances are your account is deleted. Purges of the databases are done regularly. You will have to create a new forum account and you should be all set.

Any ideas on better looking exhaust bolts?

Stainless gets brittle with heat cycles, stainless nuts would be OK but for the studs it's probably better to not use stainless.
People do use stainless but I won't. Anything is probably OK if they get some anti-sieze and take them out to free them up once or twice a decade. Letting them corrode in place for twenty or so years is the real killer.

Most materials (metals) do that as well, stainless 300 series becomes brittle when it heats between 800-1600f during its cycles. Not sure what the head sees during normal run time. I think the key is high temp anti seize, and change the hardware every couple years.
 
You could always use brass/bronze nuts, readily available in different acorn shapes or easily turned up on a lathe and get them chromed to suit.Bronze was the traditional material for exhaust manifold nuts probably before coppercote became commonplace
