Would anyone by chance have info on the torque sequence for a 1971 50 hp Evinrude Lark. I am installing a new head gasket and have the proper ft-lb specs but my manual only indicates tightening them evenly in three rounds starting at half of full torque, then 3/4, then full torque. If there is a correct number sequence I would just assume do it right. Any help would be greatly appreciated! Thank you.
 
Start from the middle and work your way out in a spiral pattern following the torque specs you have. Then re-torque after 10 hrs.
