It depends on when the engine was made. It also depends on if it is flat head or overhead valve engine. If it is a flathead it torques to 15 foot pounds. Tighten in a crisscross pattern. If it is not an 8 hp flathead click the link and look up your model.

The Vanguard series is rated at 6.5 HP. Most small engines these days are no longer rated by HP but, rather torque. Several models of Briggs 205cc engines are rated at either 8 or 9 ft/lbs of torque. I can also add that the "Intek" and "Polar Force" series of the 205cc class are rated at 9 ft/lbs torque and 7.5 HP.
Cylinder Head Torque is 190 inch pounds or 22.0nm

For a 3.5 hp Briggs and Stratton engine, the torque setting for the connecting rod bolts is typically around 200 to 220 inch-pounds. It's essential to follow the manufacturer's specifications for the specific engine model, as torque values can vary. Always ensure that you use a calibrated torque wrench for accurate measurements during assembly.
The torque sequence for a single cylinder Briggs and Stratton engine horizontal shaft head is increments of 2's for hp and 1's for head bolts. That makes 11 head bolts for an 18 hp.
