Default 2.0 heads on sti block

Im going to be putting 2.0 heads on a sti block but was wondering what gasket kit i would need to use for this. Would it be a 2.5 or 2.0?

Well im guessing i would have to use a 2.5 gasket kit for the motor and maybe use 2.0 head gaskets. Anyone?

i think alot of people use cometic headgaskets designed for this. That is what mine has. I did not do the swap so cant give you a 100 percent for sure answer.

you can choose which one you want. Believe me you will want the higher compression if you don't plan on running 25+lbs of boost. I got mine from cometic they have a 2.5l 60thousandths gasket, the of boost response was great and on boost was even better. I was pushing 22lbs to about 5k tapering to 14lbs at red. I believe the non turbo 2.5rs gasket is the same thickness so that would be a good place to start. Dont forget copper gasket spray. by the way, 2.6l with wrx heads "stock ones." td04 20+lbs before 2500rpm.
Can anybody say torque. WOW. but wasn't worth going past 5750rpms. better to just shift. Hope this helped.
ps make sure you trough the stock pistons in the garbage.
