I feel dumb as **** ... I have no idea which side of the piston is intake and exhaust. How do you also figure out cylinder number?

 

Pistons arent cylinder specific.

 

intake valves have deeper reliefs than the exhaust valve relief. what pistons are you trying to figure out? the stock pistons usually have an IN stamped on the intake side.. make sure you put them on the rod the right way, there should be an oiling hole in the rod so it does matter how you assembke it.

So the rod has to be a certain way too? The oiling hole faces which way?

 

Oil orifice in the rod faces the intake side, same way as the IN on the piston.

There's also an on the piston that points to the front/pulley side of the engine.
