Hughes Edelbrock heads : Smallblock

WOW... have you guys and gals seen the flow #'s from the Fully CNC'd and Big Mouth heads ????
- Has anybody used the Big Mouths yet ?.. Pros/Cons....
- Would the Big Mouths be to much for a stock stroke engine ... .060 over ... cam upgrade .... headers .... 4bbl etc...
-Should i go with the Fully CNC'd heads instead ....
-Should i go with 2.05 or 2.08 intake valves ...
-Thanks
