If they are then I would say yes. If they are just copies then idk. W-Body store doesn't even list how big the primaries are. Someone should pm that guy and have him measure them.
He claims they are 1.75" primaries.
My SSAC (SDO-6802 from China aka SLP knockoffs) were 1.625" primaries IIRC.
Speed Daddy (SDO-6802 from China) claims they are 1.5" primaries but I believe that to be wrong.
OBX (The Pacesetter knockoff headers) might be 1.75" because actual pacesetters were.
