cylinder head gaskets do not fit 6.0! Reassembled my engine and ran it with these head gaskets and every piston is damaged and both heads are garbage now. Of course I had to make sure the shim holes were big enough before screwing in the heads, I shouldn't have had this problem unless the description said it would fit a 6.0. My car broke down and I will never buy from this company again. All gasket specifications should be listed here and readily available.
