03 2.0fpred wrx!!

Default my 2.5 motor build, and questions?

ok i am putting together a sti 2.5 motor for my wrx. all the internals are going to be forged. i am shooting for 500whp. ok first off i am going to be using the stock wrx heads with this application, will the cr need to be changed by a gasket or i have heard that they have pistons that will let u keep the stock cr. i am going to be running the fp red turbo, on 93 and a c16 tune. so pretty much my concern is the cr will it be fine or need to be lowered, any advice will be helpful...thanks
