Noisy valve train

My valve-train seems noisy, I have not opened up my valve cover to take a look but I have a pic of a set I have laying around. My assumption is that this is worn out, as to how oval it is. When I look at my rockers on the engine and if I find something like this, I assume time for new ones. If this is the case, what brand do you guys recommend?
