Post Is BIGGER really better????

For street/strip use of a small block 400ci, what would be the biggest valve size you can go with?? People tell me that bigger valves, such as 2.08 are not that great for the street, and people tell me its good because your motor breaths better. What exactly happens when you go with too large of a valve size? I figure, a 396 big block motor comes with stock 2.07 intake valves and has almost the same stroke and piston size as my small block 400, and they are torque monsters. Im going to be running 6 inch rods also, so the rod ratio will be close too. I have a set of Brodix heads with 2.08 intake valves, should I use them on my 400, or is that too much? Any info will help, thanx.
