Here's your answer in the rule book:

b) Valve covers may be modified only to accommodate a breather and/or filler.

c) A pressure accumulator such as an Accusump may be used.

d) Oil pans and all related items such as baffles, pickup, pump and scrapers may be added/replaced

with others of unrestricted origin. (No dry sumps unless OEM.)
