I bought a set of the Mr G and a set of the Cometics from summit for the same motor,they where the same gasket Cometics where quite a bit more money I posted a thread on here about that then, one of the members stated he use to work for Mr G and they laid him off because they where starting to buy all thier parts from China suppliers and he didn't think that there MLS head gaskets would be made by Cometic anymore Do a search for tha post
