I have a blown 3.2 Carrera with stock heads (only twin plugged) and they have held up fine @ 1.25bar of boost quite happily. It's pretty rare to see these crack in a forced induction application... many guys running around with them with over 600+HP (Mike, Juan, Glenn etc). Unless you plan to run crazy levels of boost over 30-40psi, they're fine.
