Building a 600 twin. Do the 94-96 cylinders have more out of the box potential than the 97 up ones? Seems the older ones have larger reeds but the newer ones have the third exhaust ports. opinions? facts?

97 and up have better out of the box porting. 97 and up heads also have built in spot for the thermoster that is better then the inline system the prior heads had.

oh and intake boots for the 96 and older are no longer available so they are getting scarce to find a good set.
