    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.

Has anyone put an 1150 head on an 1100 engine? Can it be done? If it can, is it worth the effort?
 
Yes it will fit straight on, but it makes little difference , you are better off just using 1150 cams .

One minor difference is that the '80 and '81 1100 had a mechanical tach that was driven off the exhaust cam...later models did not have this.

You have to change the studs. 1100 are different lenghts. 1150 are all the same. The 1150 will flow much better than an 1100 head. I did some port work on my 1100 head and it's still not as big as a stock 1150 head.
 
Another advantage of the 1150 head is the valve cover. Much easier off and on. If I had a spare 1150 head I would use it if I had the engine apart already.
 
I'm getting ready to install a 1260 block on an 82 1100 engine I've had sitting around. Got a spare 1150 top end and figured I could make even more power that way.
