GM Head Gasket When I received my full gasket set I noticed that the head gaskets were sold seperate 12558809 and 12558810 for the left and right head gaskets. I came across a website that sold the gaskets in a set 12498543, they claim the compressed thickness was .056 which is exactly what I need. My question is, are the gaskets that I received the same as the ones that are included in kit? The kit is from GM Performance Parts and they say they are Composition OEM replacement gaskets for 5.7L engines.
