The 1.88 valve helps with air velocity which results in a better throttle response and possible mileage gains on stock engines or very mild cam changes.
The 2.02 is best suited to higher rpm useage. The difference in valves, performance wise is small. Like you mentioned, it is in the combonation of the build.
