All I did with my old T28 was to get the manifold re-studded. Wasn't hard. I just put it into an engineer who left the old studs in, but cut them off flush and planed over the surface before tapping it for the new spacing. The new studs overlap the old ones slightly, but this isn't a problem. I think I paid £30-40 for that to be done.
