    Decking the block would move the piston up, increasing compression. One guy on here suggested a thicker head gasket. Never tried this so I would not know.

    Are you at Hunter Peterbilt in Erie,Pa? If not get there and have Randy(only Randy) look at it he is one of the best Cat men in a factory shop you'll find. If you can't get there try to call him he'll help all he can.

    You need to counter bore your cylinders and then shim them back up.

    Probably worth buying new liners too.
