Default 2.055 Valves on 4.00" bore?

I just picked up a 2002 lq4, would a 2.055 valve work fine on the stock bore? I was told a 2.08" valve like on the stage III 6.0L head would cause shrouding, and I know 2.02 valve is recommended. What do you guys think about 2.055" on a stage III head?

I ran a 2.08 valve on an LS1 bore seemed to work OK for me. They are now on my LS2 and are making more power.

Yes you can use 2.055 and 2.08 work fine as well. No shrouding issue on 4.00 bore
