Quick question, and I know this may be more complicated than this, but as a generic rule of thumb would you need a better scavenging header setup for a cam with more or less overlap?

assume generally the same cam specs for a cam with 80 degrees overlap compared to one with say 70 degrees. only change being lobe separation. you you need more scavenging going to the smaller overlap to be as efficient?
