5.3 head gasket guestion?

I dug up the numbers in Oreillys site, for the head set (2000 GMC 5.3). There is a number listed for 99-01 (HS9292PT).... also a listing for 02-08 (HS26191PT). Both are Felpro numbers, but it appears that the 02 up has the MLS gaskets ? My question, is will the later set work with my 2000 engine, or are there differences in some of the other gaskets in the set? Thanks for any thoughts on this.... Longhorn

Old style heads have this little notch and use a graphite gasket, not the MLS gasket that the newer style uses. The metal MLS gasket will leak on that head.
