Ok had the supercharger gears for wp fail and engine overheated. I've now got exhaust in the coolant. Who is a reputable supplier of reworked heads?

What makes you think the damage is limited to just head? My auto tech buddies cautioned me about repairing/rebuilding any engine that suffered from overheating or oiling issues. The odds were too high the engine was compromised in a way that made any rebuild/repair too much of a risk.

 

Way offers rebuild service, or simply find a local machine shop to do the testing and rebuild work.

Besides performance heads and e-bay offerings, there isn't that much in the way of buying an already rebuilt head to exchange.

As a side note, overheated mini engines are notorious for head warpage and cracking, which in turn breaks the gasket seal, so make sure the head deck is checked for true and the entire head is inspected for cracks.

While it's possible, it's not normal to damage the bottom end from a W/P failure overheat, so I wouldn't worry much about the short block. With these blocks still being cast iron, you have to put a considerable amount of heat into it to do much damage there.
