I have a 99 vette that will run a vortech supercharger and I'm trying to make a decision between the LS6 or the XR265HR camshafts. Keep in mine that I'm not swapping the heads they will remain stock, it's just a cam swap it'll be doing. Is it worth the extra money to get something alittle better then the LS6? Also can I run 02-04 LS6 Valvesprings with the XR265HR camshaft?
