ARP head studs, either a OEM 4agze headgasket (can get via toyota dealer of amayama) or use a 0.8mm mls trd headgasket (can get off gumtree) to pick up a little more compression. Ensure both block and head surface are in good condition (head could be skimmed while off anyways).
Also while head is off wouldn't hurt to replace the valve stem seals and get a cut on the valve faces while it's at the machine shop getting the head face machined. (don't let them take too much off the head face surface, just a light skim).
