A lot of noise you hear are due to headers.
There are two types of rockers. There are non adjustable (like stock rockers), and adjustable.
Non adjustable are to be torqued to a specific number (usually 22-ft lbs), and the pushrod will change the preload.
Adjustable rockers have a lock nut, and can be adjusted up and down as they are not set at a specific torque. The height it is to be set as it is determined by the footprint from the tip of the rocker where it wipes on the valve stem tip. The pushrod length is then determined after the proper footprint has been achieved.
You can free up some HP with roller rockers as they reduce the friction. There are however plenty of people making good power with stock rockers. I bought aftermarket adjustable roller rockers, and if I did it again, I would more than likely stay with stock rockers unless I was looking for a different rocker ratio.
