These are race covers, and the spec sheet reads that way: sand cast aluminum, natural finish, and none of the street conveniences. No baffles, no grommets and no filler cap, because a race engine handles breathing through a dedicated evacuation setup rather than a PCV grommet in the cover. They are cut to clear the tall valvetrain on Big Victor cylinder heads.
