Yes, if it didn't do this before, then it sounds like it got too hot and blew a head gasket.
They did have a problem with intake manifolds on these 3.8 engines that caused coolant to leak into the intake but that would have started earlier. It will be obvious when the intake is removed. The valley will be full of coolant if that were the case.
