All the major Packard vendors carry headgaskets, as well as Egge.

Unless you cc or otherwise check your head to determine how much, if any. it might have been surfaced in the past, I'd be very reluctant to resurface it unless the surface is damaged. It is surprising how much these heads can be off and still pull down and seal OK. If you do have it surfaced be sure to check for valve clearance before bolting it down, otherewise you risk bending the heads on some or all valves. There are a couple of ways to do this; one is to lay the head without any nuts installed on the block with the old headgasket and crank the engne. If the head rocks, you're milled too much and run out of clearance for the valves. Another way is to place modeling clay on the high edge of the valves, install the head, again without fasteners, crank the engine over gently, remove the head and check the "crush" on the clay.
