Default Dealer Screw Up: WRX Headgasket on an STi

OK, we ordered a complete gasket kit for an 04 STi for my friend's engine rebuild. Turns out the dealer sold her a 04-05 WRX master gasket kit. We didn't catch it until we found that the intake cam gaskets weren't right. The thing I'm most concerned about is that there are now 04-05 WRX (2.0L, right? I'm an NA guy) on an 04 STi (2.5L). Is this at all safe and reliable or are we about to raise hell with the dealership and have to tear the engine down again?

This has been the friggen build from hell....

it will not work. the metal "ring" of unused gasket will burn off and raise hell with you pistons, vavles, head, turbo. ive seen this happen allot on customer built yamaha's with MLS gaskets.

That's the crazy thing, I would swear the bore on the HG was correct but it shouldn't be for 2.0L vs 2.5L, right?

snap-on makes a great bore scope/camera you could use to look in threw the plug hole(yes it will make the turn and yes its that good) and see if the gaskets is "to small". do you know any shops that have and would let you barrow one?
