Any 500hp at the engine SB build that I've seen has at least 190s. 500 at the wheels? Jump up to the 200s with a solid roller no question.

I don't think a valve would really be the limiting factor, it's got to be the port behind it. A valve just covers a hole, and a 1.9" valve should flow as much cfm as a 1.9" pipe with an obstruction in front of it, minus the thickness of the valve stem. And obviously with a bigger valve there is more room back there to scoop out the port.
