I've been doing my research on valve adjusting. I understand it is a simple procedure. However, how do I tell the intake and exhaust valves apart?

Thanks!

Each valve lines up with the appropriate port on the head. So just look across the head at the intake and exhaust header and you'll see which valve is which.
