you dont want to go bigger than a 2.02 intake valve. You may not be able to go that large if you plan on changing the cam. It just depends on what size cam you get

The factory heads are junk by themselves. You put big valves in there and it will kill the velocity of the air, causing torque loss. Get some good heads. AFR's are the way to go.
