By: "tear it down," Doug, do you mean just the head gasket R&R or the whole engine?
If just the head, as mgbtf suggested, the Payen head set is about all you'll need. Check the block and head for any warpage/unevenness.
Keep all pushrods/lifters in order of removal, so they go back in their original places. I just use masking tape to make "tags" for numbering pushrods and egg cartons for lifters, valves and springs, etc.
I would likely also hand lap the valve seats while it's apart. Just one of those "might-as-well" things.
