I dont know which gaskets your reffering to but these are the only thin gaskets Im aware of from mr. gasket and they are advertised at 4.140 bore size.The actual measurement is right around 4.150 bore size,you can see in the pic its a little larger than my caliper-these also measure .032-.035 for thickness out of the wrapper,the mopar gaskets are different like you stated.

I don't know the number on them either. They came in a kit I bought a couple of yrs. ago that I didn't use. I looked all over them and couldn't find a number. When I bought them the salesman told me they were they were the thin ones so that's what I was going by. I measured the thickness and they measured .044 out of the package so I'm not sure how much that would compress to but I doubt they will go all the way down in the .020's like he told me. The bore is also bigger than I was told. I measured them at 4.078-4.081 Sorry about the misinformation. I should have measured them before I spoke. I also should know better than take a salesman's word as gospel.:bootysha:
