Need Cam advice on my 360 with Edelbrock Heads!!

The problem with the Edelbrock heads is the amount of port volume as listed at 170 ccs and the stock iron heads is 150 ccs which is a bunch and more and as the port volume goes up the efficentcy goes down and more so with the larger valves being 2.02 and 1.60 verses 1.88 and 1.60. Flow isn't everything and neither is port volume. The key is to match all the componets and then you'll have a engine that will get the job done. IMO you would have been better off with the stock heads and had some work done than to go to bigger runner heads and larger valves, and then try to match a cam to the bigger heads. As has been stated that you'll need to stay smaller with the camshaft on duration to help the heads work better otherwise I think you'll be backing up.
IMO why would you need a set of heads that are capable of 7000 + rpm's and a cam thats good to 5500 rpm's if you won't get the engine there, sounds like a waste of some parts to me. Or if you get a cam to work with the heads then streetability will go out the window and more compression will be needed to help the other parts work. Pretty much as already been stated previously.
