Couple questions about eq heads?

I don't quite understand what you are saying, all 10 bolts are installed in the covers... Thanks

I mean you can use LA 5 bolt valve covers on the 10 bolt heads because the 5 bolts that LA covers use line up with 5 of the EQ or Magnum bolt holes.
These are fabbed LA style 5 bolt covers on the EQ heads and an LA style intake on the CH318B heads.
