As for the shrouding...Its not here yet, but he said they have tried different shrouds, fans, etc...I'll know more when it gets here.

220 + is still not overheating and any of the suggestions above could be the solution. If in fact it is spewing or clearly ready to boil over, then I stick by my suggestion to check for the head gasket leak. It's a simple chemical test that would rule that out.
