Tech Craft in either San Mateo or Redwood City. (I forget exactly how far up the Peninsula they are). They're pretty good; Bontempi from High Performance House told me he uses them for his street motors. They're right next to Elgin Cams, and used to be associated with each other long ago.

I don't know if they do welding on the heads or not, so it's possible you'll wind up SOL if they're cracked.
