Start up and get the engine to operating temp, cover radiator if needed and check for any problems during the period. Try for the shortest time. Operate at 3/4 throttle in 4th gear no load for 15 minutes. 45 minutes at 3/4 throttle on light work. Run it 2 hours full throttle on medium to heavy work. Check for leaks and check valve adjustment. May as well check the head bolt torque when doing the valves. With a victor type head gasket it may not change in 3 or 4 hours, but better safe than sorry.
