Not that easy my friend. You're talking bout Subaru's boxer engine. If just switching out the heads would make 270~300hp, tons of Subaru ppl are making 300hp (NA). But the fact is different. Even w all the bolt ons, head port&polish, cams, High comp Pistons, NA EJ25 is pushing average of 195hp-ish.
