Going to a 2.02" valve will be beneficial if you are looking to get 350 HP or more. My last head with 2.02" intake valves and my billet lumps flowed a little over 290 CFM. But like any oversize valve, if you don't open the bowl up to correspond with the larger valve you won't get the maximum benefits from putting them in. Also, as Hank mentioned, the +.100 long valves are what I use. They also help with the larger cams that you will typically use when seeking HP in the range I mentioned.
