Stacked carb gaskets?

Hi,
I just had the carb on my 53 custom line with the straight six rebuilt.
I went to remove the old gasket to reinstall it and found that there was no less than 6 gaskets stacked together.
Is there a reason that this was done?
Would it have been done to isolate the carb more from the hot manifold?
They were not glued together, they did have a staple through them on each side.
This was my great grandmother's car and all the guys that I know would have worked on it have passed on.
Thanks in advance for any knowledge of why this may have been done

Yes you are correct the multiple gaskets are used to isolate the carb from the heat of the intake / exhaust manifolds. The staples used is how many of these thick carb base gaskets were made for the mid 1970's up emissions equipped engines. Good luck :nod:
 
The thickness will change the idle speed. A shorter height will cause a fast idle I could not adjust for. So i re-installed my original gasket/spacer stack and it straightened out. It had to do with the linkage travel.
