I had the plate on my carb setup for heat soak. I knew the efi didn't need it but knowing the ecm is on the tb I figured it wouldn't hurt to keep the heat off. Plus all my linkages where set up with the spacer so I figured why not. Not real reasoning behind it other than those and I like the taller carb look.

Now the single or dual intake is a hard one and prob best answered by someone else. Mine is an older Holley that is completely open right to the tb. In other words no divider. I feel like the dual plane is best suited for my needs for low end torque considering it's a truck and not a race car and rarely sees 6500 Rpms. But it does pull hard to 6500. I also feel that the open plenum is the main reason I didn't hurt two cylinders when that injector stopped firing. In a single plane it would of starved those two cylinders even at idle where my truck ran fine at idle and low Rpms. Again this is just opinions.
