    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...

    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.

How can I tell if rocker arms have been hard welded?

Is there a way to tell if a set of rocker arms have been hard welded? Also, will putting a "new" set of hard welded rockers on a used camshaft be fine? Also, I have read that hard welded rockers can actually eat up some camshafts depending on how hard the cam is. "Hot Cams" is the brand I read about having that problem. My cams are old Vance & Hines. Think that would be an issue? They are .340 lift. The rockers still look great but my head builder might be putting in heavier springs and I would hate for those to eat up my rockers. Thanks
 
Look around the edge of the pad. You should be able to tell. Old V&H cams would be fine.

Thanks. I compared mine to another stock set and they look the same. My machinist said I should be fine without the hardweld rockers with just a .340 cam.
 
You will be fine .340 lift cams are very mild cams. I would install a set of APE valve springs and titanium retainers. Then have the spring pressure set a 45lbs.
 
Also if you have hard weld cams then use hard weld rockers and you have billet cams use stock rockers.
