I've been looking at this head for almost 14 years, thinking it to be useless.  But what do you think?  Hopefully the pictures will show installation of hardened seats for 1.78 intake and get this, 1.45 exhaust.  It looks to me like a significant amount of combustion chamber has been bored away, leaving some sharp edges to help assure detonation.  Your input will be appreciated.
