As with any hed gasket problem as long as you get to the problem early enough as to not have any further major damage happen due to driving/running the vehicle too long after the head gasket blows I would say no to a complete engine rebiuld. Oil must be drained and new oil filter replaced, cylinder head must be sent out whiile you are at it send out the good head too and have the magnafluxed for cracks, have the engine to head surface checked for cracks as well, replace as needed, install cylinder head gasket and intake gasket set retorque and or replace head bolts as per manufacturers specs....happy motoring.
