Default valve ?

i have a set of 5.3s that are being p&p is it worth the cost to go to the 2.02 valves on the intake side? i have a stock 2.00 in my ls1 heads i was going to go to just the 2.00 but what hp number would i really look at going to the 2.02s vs 2.00?

i went with 2.00", my machinist said the 2.02 would be cutting the seats awfully thin.
