Hey everyone ive been searching a bunch and cant really find my answer

So I have a 02 wrx with a 2.0/2.5 hybrid. The problem is i have a blown head gasket on the passenger side. I am going to be pulling the engine and replacing both head gaskets now my question is since i am only pulling the heads off and replacing the head gasket what other gaskets do I need. Im wondering if i can just get the ones i need instead of 150 when i only need a few.

as of now the only gaskets i can think of that i need are
all the exhaust gakets
tgv gaskets upper and lower
head gaskets
valve cover gaskets

what other gaskets should i get
