the kit comes with a new style front chain and new style front sprockets - but the large sprocket does not have the cam position trigger cast on it, so the installation instructions for the very early engines say to just throw the two new sprockets and chain away and use the old ones.
the older engines still had a cam position sensor in the cam cover - on bikes since then the cam cover is completely pointless - nothing in it
the andrews kit that does the same thing but uses special cams has a new style chain sprocket WITH the cam position trigger cast on it. the andrews kits costs more due to new special cams.
so the REAL question is this - can the andrews sprocket with the cam position trigger cast on it be used with the hd kit? "will the andrews sprocket fit the old cams?" if so its obvious that the new chains wear better so it really should pay.. the andrews part number is 216015 - if somebody has the part in hand we will all know.. note that even with the andrews 07 chain kit - this sprocket is a add on to the order and is specifically for the early years.
