I have been looking for a bevel gauge but the only one I can find is one from SVMT and it is like $200. Do you know if there are cheaper ones out there?
Also what are the dementions of the race stock WC?
It is not as important what the bevel actually is, more that it is even down the ski. also concavity of the base (if it exists) in the tip or tail or both is not an issue as long as your bases are flat about 1" in from each edge, but convexity is a big problem and the ski need to be sent back for a warranty exchange if your bases are convex.
if I were you, i would go ski on the skis the way they are after you clean them well and wax them and see how they ski. Although i would make sure to run a stone flat down the base edge to make sure there is no hanging burr.
if you like 'em leave 'em alone. If you don't like the tune, at least you'll know what you don't like and then can go about changing them by either increasing the side edge bevel only or stone grinding them and changing the base bevel begining with a .5/3 and if you don't like them try a .7.
Also really concentratre on what you do or don't like. if they hook up smotthly and realease smoothly but don't have as much edge grip as you'd like you only need to got to a 3 degree side edge bevel and there is no need to touch the base bevel.
If however, they are very slippery and you can't get them to hook up without an exterme amount of inclination/angulation you have too much base bevel and need to have them stoneground and tuned both side & base edge form scratch.
if they are really grabby and unpredictable (be sure to remove any hanging burr from the manufacturing process before you ski on them to rule this out as a cause) you probably need more base bevel.
Even with an untrained eye you can use a truebar to see if the skis have any base edge bevel or not. if there is absolutly no light coming through under the true bar when laid flat against the base and base edge with a light source behind the truebar., then you have no base bevel and must grind & tune the skis completely.
If however there is an even amount of light coming through the bar on both base edges, go ski 'em & see what you think!!!!
