Default 07 Impreza head gasket parts list?

I recently bought an 07 Impreza 2.5 Auto with 120k miles on it with a head gasket going bad.. I'm to the point where I want to try and fix it myself.. I've done some middle of the road projects but nothing this big and I just wanted some input on what I should expect or any tips etc.

I found a tutorial video of someone replacing the same year and I'm going to follow that along with a haynes manual

Am I missing anything on what I should replace while I have it all torn apart?

Water pump, timing belt + pulleys, thermostat?

Really any info will be appreciated

if you are able to pull the engine it can be less painful. Still quite a bit of work for a shade tree mechanic.

I work on anything and I WONT do another and I had access to a lift and a Subaru tech.

Good Luck!!!

Great parts list and really buttons up a EJ25 for a solid 100K more miles.

Ok, but my question is, what type of head gasket are you using for this? I'm in the same situation, researching options. Felpro?

Good list. I forgot about thermostat

Now if I could figure out how to paste a table in, I'd update the thread with part numbers...

That's what I generally do. Search for a couple of the part numbers in one query.

The things you got though, got a link? Online vendors tend to have a pile of the same thing.

I'm doing headgaskets right now and I decided to buy the 1a auto headgasket kit but since it's only $80 and comes with many seals and gaskets, I don't trust the head gaskets for that price so I bought the awdauto six star head gaskets.
