For my 2 cents, air speed is far more important than cfm. If you don't have air speed you have a lazy engine. cfm is important, but air speed is King!
I am going to guess it would run far better with a 1.88" intake valve than it will with 2.02"s
In you combination I wouldn't use a larger valve. Everyone get caught up in the bigger is better on valve sizes, cam sizes, and carb sizes. The truth is most guys have all of the above and
wonder why it doesn't run that well. It's just like baking a cake you need to have the right portion of ingredients to get the best possible outcome.
