68RS350

I've been doing a lot of research on the 6.0L and L92 set ups. I have a 2000 LQ4 motor now w/ the cast iron heads. I saw that in 01 and later they added an aluminum head that was and LS6 style. Would a set of LS6 heads be better than the L92's? I've seen the dyno numbers from car crafts article. the Stock iron heads from an LQ4 made 483hp @ 6000rpm and 450lb-ft @ 5000rpm. The L92's produced all the hp gain around 6800rpm. My motor will never see that on the street. I was wondering with a nice cam if the LS6 heads w/ a FAST intake a 90mm throttle body should compare to those number with the stock heads right? If i missed anything let me know.

Thanks
