Port my Eddy's or Stroke to 408?

I do 915 j heads 71-72 castings for 1200 a pair and they flow 287cfm at .600
i do this for a living. add 250 for a used set of 915j cores (always on ebay) my 1200 = 1450 for a race heads. eddys are 1200 pair 1200 for the same port i do = 2400. eddys are better for street use hands down but for bang for buck. 915j 's all the way. almost a grand less and higher flow numbers most eddys flow at best 277 at .600. wanna get rid of 50lbs buy a fiberglass hood usbody source 500 bucks youll still have 450 left.
