I'm not sure, but I don't think the 2.02" valves were "stock" until the
introduction of the 302ci in the Camaro, and the LT-1 in the Corvette.
Most of the early GM heads that I have seen (that were still "stock") had
1.94" or smaller (intake valves). Unless you are doing something really
extreme with a small block (i.e. high RPM stuff, above 5000 RPM or so, or
large displacement like the 426ci small blocks), the big valves will not do
a lot for you. The 1.94" will normally give better low RPM performance.
Just my $.02 worth of opinion
