When my HG blew my cab heat was also intermittent - when accelerating it blew cold air when there should have been heat, when idling, heat worked fine. From what I understand, the coolant system is getting air bound due to the excess pressure in the coolant system with blown HG. This is a simple test that might help diagnose.
If it is your head gasket, make sure to get the heads machined and pressure tested and try very hard to get the dealer to put in ARPs and do an EGR delete kit to help with the reliability of the engine.
