Can you post a pic of the fouled plugs? I suspect valve stem seals, because the back ones are often the first to go in the sbc's that I'm used to. Here's a good reference on fouled plugs. spark plug reference
So I would suspect the plugs to be black and kind of wet or sticky. Am I right?

Hmm.... sounds like a fuel issue, mixed with maybe your valve seats? Does it puff black smoke when running? Could mean your rings are bad. Have you done any upgrades on the fuel system, like the new delphi spider injector?
