Change efi or change intakes????

I'm running ez 1.0 on my 416. I've always fought with low vacuum. I was going to swap my rpm dual plane with a victor single but recently spoke with a member here who suggested switching to a Holley or fitech system that doesn't require a strong vacuum signal. I was convinced but the more I read the more I find that all tbi systems prefer single planes.
any thoughts ?

if u stop and think about it, it seems a single plane would be better w/ a throttle body. the open plenum seems as it would work better to me. I`m running a torquer 2, w/ the low flowing runners opened up.. my cam doesn`t have as much vacuum as fast says they`d like, but so far so good.
