Default getting head gasket replaced. Needs some tips/advice.

Hello so my 2017 STI unfortunately was having head gasket issues at 50k miles. Always changed my oil every 2.5k-3k miles, did coolant flush at 30k. Anyways long story short I'm getting a head gasket replaced. I'm getting it taken to a machine shop. Question is.....is the OEM head gasket on a 2017 STI an MLS/graphite/composite? I'm looking to go with MLS but can confirm if OEM is already MLS. I'm also going to switch over to ARP head studs.

While I'm at it I'm going to change out the timing belt and water pump, radiator, hoses, and thermostat. So far I'm thinking of koyorad radiator and gates timing belt and water pump kit. Thoughts and opinion will be greatly
appreciated.

X2 on the MLS head gaskets.
Go with OEM MLS gaskets, they shouldn't ever fail again unless they are installed improperly, or you beat the tar out of the car every day.
Don't buy the Gates kit, they use Chinese bearings that WILL fail.
The Aisin timing belt kits are nice and high quality, and 100% made in Japan. They are also cheaper than a kit from Subaru.
If you go with a Koyorad radiator, make sure to straighten out any bent or crushed fins before installation.
