you don't have to have the head checked but its recommended. the head bolts are supposed to be torqued in counterclockwise order from the inside bolts to the outside bolts. torque them in order in three stages to 18 ft/lbs then to 27 ft/lbs then an additional 120 degrees except the front right stud which you torque to 90 degrees
it could be a blown gasket, cracked head or water in the exhaust
The head gasket torque specification for a 1984 Ski-Doo SS25 typically ranges from 15 to 20 ft-lbs (20 to 27 Nm). It's important to follow the manufacturer's guidelines for the specific engine model, and to tighten the bolts in the correct sequence to ensure even pressure. Always refer to a service manual for precise instructions and specifications.
