If you pop in the hotter cams I would defiantly buy them. They just add more cooling and lubrication to the top end. They are really only necessary once you start modding the engine heavily. With a stage 1 or stage 2 with stock cams it's not really necessary however some guys like to have the confidence of better lubing up top for track days, extended high speed runs, etc. But for the street I wouldn't bother. Put it this way the GSXR1100 which our engine is based on never had them stock and I've never heard of them suddenly exploding on the highway from lack of top end lubrication and they have much hotter cams. My friend had some on his 1982 Katana(the original one) 1100 that he bored out and popped in a high compression piston kit, and a whole bunch of other stuff but thats with a heavily modified engine that he used to race, but his other street bikes never had them. Hey, if your worried about top end lubrication throw them in there, they can't hurt anything and are easy to install. However probably 50% of people pop it on there for "bling" not "zing".
If you have the stock cams I could think of alot of other things you could spend that $220 that will give more tangible performance increases such as towards a stage 2 jet kit or an advancer or stepped headers or something. Don't worry if you put them on there and you don't need them, you're not making a mistake or anything, it just saves a step later if you mod the engine.
