Intake Manifold Question

I had an Offy dual quad set up on a 360 back in 1986 when I was 17. My biggest problem is that I had two carbs I had were put together from about 5 "parts" carbs that I had. Once I was able to afford two good carbs it ran really well. Since then, every dual quad car I have had (I've owned three hemis) I buy two new carbs right off the bat.
