Yep, although this is "just" a refurb rather than any porting work there will be a noticable improvement - don't underestimate what a good head refurb with fresh valve seat and head cuts and a total de-coke can do for both performance and economy.
As an example, if you look at the pic showing the valves you'll see how coked up the exhaust valves are and how little decent seat contact was being made before. This is pretty typical of most H22 heads out there with the mileage that is on them. Intakes are difficult to get shots of the wear on the valve head angle cut but both the intake and exhaust valves not seating as well as they can will cause a gradual loss in absolute compression.
