WF intake manifold

I just acquired a new World Formula motor and noticed that the quality of the intake manifold, which is a sand casting, seems to belie the quality of the rest of the castings, which I believe are investment castings. My question here is: Does IKF allow you to clean up the interior passage of the intake manifold and improve the match at the port juncture? My 08 IKF rulebook makes no reference to the intake manifold.

OK, question answered: I couldn't find that clarification in the 08 rulebook. Thanks, I'll leave it alone. Just curious; what is the WKA's take on this?
