From what I've read elsewhere, and heard from my local head shop, the stock
exhaust seats are 'marginal' at best. If you plan to run the car at high
speeds (for an Alpine that means on any freeway) and already have the head
off, now's the time to replace them. A good head shop should be able to
recommend a replacement seat.
