Overall Assessment

Customers highly value the product for its quality, usability, and effectiveness. The carburetor spacer has been praised for its excellent craftsmanship, heavy-duty construction, and perfect fit. The product's usability is evident in its ability to increase airflow, enhance performance, prevent fuel percolation, and raise carburetors to desired heights. It also assists in course correction and dealing with the siphoning of gas. Several clients have appreciated its application in custom builds. Accolades include improving the looks and performance of vehicles at a beneficial price point. Minor modifications were occasionally required but otherwise, investor satisfaction is high, with multiple customers willing to repurchase.

Would a single plenum spacer defeat the purpose of a dual plane manifold or is this better for a single plane manifold? I'm running an Edelbrock 2701 Performer EPS manifold with a Holley carb. I basically just want the motor taller for aesthetics but without decreasing my current performance.
