I currently run an open 1/2" phenolic carb spacer with my dual plane Edelbrock Performer RPM intake. I'd like to try a tapered 4 hole spacer and a divided spacer to compare performance at part throttle as well as mid and top end.

For the divided spacers, the only ones I'm seeing on Summit are these 2 by Edelbrock. Good choice? How do I know if I need the one with a single bolt hole in each corner vs the one with two bolt holes in each corner for my QF holley style carb?
