He probably wanted to know what rocker they were to make sure you had sufficent valve spring clearance (if your changes springs to work with the cam). they look like Crane Energizers of Omega's from the pic's. all Scorpions have the "scorpion as pictured above"
I have had great luck with the Scorpions, they will take a lot of spring pressure, clear large OD valve springs and are high quality, don't skimp on your rockers or you'll be sorry.
