In this document it says the tooling holes may be drilled to 5/8". http://www.vansaircraft.com/pdf/Wing_Wiring.pdf
Here is a picture of a W911L rib which shows two holes to the left of the first large lightening hole. I am thinking the top hole will remain as is and receive a bushing and could be used to run the pitot plumbing. The bottom hole as per the Van's document could be enlarged to 5/8" to receive another snap bushing for additional wiring. I've already made the 3/4" hole for the conduit, but was wondering about these two other holes.
