Any recommendations as to where to buy heads and/or new engine if it becomes necessary?  PO said bus was backfiring and he quit driving it; he also said he thought the valves are burned?  I don't know why he thinks that.

I haven't run through the Muir Idiot book/Bentley procedures for fuel injection yet; I did install a new battery and have lights; engine turns over but have a fuel leak under the engine.  (Sorry to bother you all; I'm not on the type2 list yet.)
