    DO NOT SIGN UP USING hotmail, outlook, gmx, sbcglobal, att, bellsouth or email.com. They delete our forum signup emails.

    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.

Did valve adjustment on 450 winter project today. Just wanted to run some of the numbers by you guys and see if you think I should get a couple of new shims.
#2 ex. is now at .04mm with 2.55 shim, #1 ex. is .03 with 2.60, and #1 intake is at .04 with 2.55 shim. I know these numbers are with specs. but should I get smaller shims so the valves are not quite so tight? terrylee
 
Definitely change the #1 exhaust - it''ll be in spec at .08. You could leave the others as they are or you could go .01 too large on the gap - either is fine as long as you're happy checking the clearances on time next time. Plus, the next size down shims might be .01 thicker than marked (this is pretty common) and you're in spec.
 
Throw the 2.55 in place of the 2.60 and order two 2.50 shims to replace the 2.55's.
 
You did not list what #2 IN is. :-k

Personally, I would probably change them. Are you using the spreadsheet I sent you? If you choose to use shims other than what it suggests, there is no problem. Just enter the size of the shim you left in there. It will just alert you that it's not what it suggested, but will accept it just fine. :o

.
 
#2 intake is .06 with 2.55. Plan on using your sheet but misplaced, so will reprint at work tomorrow. Guess I'll do as suggested and get a couple of new shims from ghost (shim club). terrylee
 
If you would like to post up all your shim sizes and clearances, maybe we can see some possible combinations you may have missed.
