Head Gasket Replacement questions

My car was overheating while stuck in traffic but when I started driving the temp went back to normal. Popped my near full radiator cap off and found oil streaks in it. Topped it off and started the car and coolant jumped out.
Rather than just doing a head gasket replacement, what other things should I swap out while im in there? I was thinking ARP Studs, some sort of performance head gasket rather than an O'rielleys or autozone one, maybe do my timing belt and all the stuff attached to that while im in there. Anybody have any links to good replacement parts for my ride?
Engine is a B16a JDM OBD-1
