Ryan,
You planning on blowing up your engine sometime soon? Or just looking for info?
I'm no swap expert but this seems to be the norm:
If you've got a 2.0 and want to go to larger displacement you can do a hybrid which involves getting a 2.5 sti shortblock or something built that's similar. You can thus use the 2.0 stock heads on the 2.5 shortblock.
If you want to do 2.5 heads though you might as well swap out your entire 2.0 for a full longblock 2.5 STI or FXT motor. Then you're getting it all at once and don't have to have extra install costs for getting the shortblock and then getting 2.5 heads installed later.

WRXisthebest,
You should do it.....I want to do a 2.5 swap too but that's a year off still. In reality didn't you say you had a friend with a Hybrid that was coming to your meet? I'm VERY interested to see that car. Hit me back,

just do some port work the stock wrx heads are prity good when you do them by them selfs but when you port them it realy wakes up the top end
