I've seen this behavior as well. The 'Room for sideheads' property is not recognized as an override of the master page. 
I think the reason is that 'Room for sideheads' is considered a property of the text flow, and not of the individual master page. 
Try setting the flow tag of your index pages to be different from the flow tag of the chapters.
