Thank you for your question.

I have checked the model number you have submitted but I could not find the model number of the engine. That should be ok. I found it is a single cylinder Briggs and Stratton with overhead valves. I have posted the sequence for all of the heads below. You should be able to match your head to the image. Once you have the proper sequence torque the bolts to 220-inch pounds. You have to step torque the bolts. This means torque the bolt to70 inch pound then 140-inch pounds then finally 220-inch pounds.

Please let me know if you need further assistance on the repair of the engine.

Here is a link to order any parts you need.
