With the heads being milled I would run the stock gm MLS head gasket set. The gm part number we use is 12498544.

Im running a set of unported 799 heads, milled 25 thou with the stock MLS headgasket that John is talking about. Also got a new EPS cam to go with em. Just measure for your pushrods, to makes sure you get the right length, and enjoy the boost in compression!
