Yes 2 small 4bbl carbs are the ticket.Keep in mind for example the dual quad set up package from Edelbrock for the Ford 289/302 recommends 2 500cfm carbs. Personally I would run 2 Edelbrock 500s. I have run them on low rise dual plane 440s and the same carbs on an M1 tunnel rammed 440. They work. I have zero experience with the small Holleys but plenty of testimonials that they work as well.
