Shimming the tensioner is a common and accepted band-aid for a worn chain or a
milled head. You can see a picture of one at
http://www.gordon-glasgow.org/Images/Shimmed_Tensioner.jpg.
Having bolts in the front cover instead of studs will make it easier to remove.
Whether you can do it without ripping up the head gasket is the big question.
I've never had much luck at it myself, but some other people have.
The manual only lists hot valve clearances, which are .008" intake and .012"
exhaust.

Hi all,
I have just bought a fully restored 1970 2000 sports. The car is
perfect except for, what I consider, noisey cam chains. I plan to remove the
rocker cover and take a look to see what could possibly be wrong, but first
would like to see if anyone can help with one or two questions.
I know that the cylinder head has had some taken off the bottom surface,
because of this I intend to place a shim under the tensioner. Has any one
had any experience with this?? Any advise would be greatly appreciated.
I have noticed that the two studs in the timing chain cover have been
replaced with bolts. Does this mean that I can get the cover off without
lifting the head?? What a bonus this would be!!!
Does any know what the tappet settings for a cold motor are??
This is my first try at this mailing list, I hope that these are not too
"frequently asked questions"
All the best, Brian.
