What is the head bolt torque pattern for a 400000 series Briggs and Stratton twin cylinder

@knuckelhead the 400000 series should be a Intek V-twin

  1. Place cylinder head gasket over alignment dowels on cylinder block.
  2. Install cylinder head assembly. Torque head bolts in sequence shown to 220 in. lbs. (25 Nm). Here is the diagram to show the pattern

Can this torque been used of Flathead engine too, engine model ,type:10T502-0833B1, itd litle hopeless to find some true information of this engine…
