Next stage of upgrades will be: Metal HG, Studs, Inatake Manifold, Cams and 740cc injectors. Hopefully, it will make close to 400whp at 20+ psi

You can make 400whp on the stock head gasket just fine. Been done plenty of times. Just make sure you have a good tuner. There's really no need to change your headgasket/studs until you pop the stock HG, it would kinda be a waste of money to do before hand IMO. If you have the funds for it already I would order it ahead of time that way if/when the stock HG goes. You already have ARP's and a metal HG ready to go on.
Also a intake manifold is pointless if your not making 400+. You gain top end power and lose your low end tq. (It does make your engine bay cleaner and cleans up the VAC/Fuel lines tho)
