Kevko pan/pump question

Since my primary motor (vintage circle track racing) is kaput, I am trying to rush a back up engine into service. I put a Kevko rear sump oil pan on it, along with their pickup. Their pickup system plugs the normal hole and runs the pickup off their custom made cover. The original cover inside has two carved out areas, the Kevko cover is smooth. Just being careful, is this a problem at all?
