Air gap small block intake -any brand testing?

I bought an Edelbrock Airgap from Hughes for my 5.9 Magnum based stroker. I did have them deep port match it to their Edy CNC chamber worked/Super Prepped heads, which were also had their hand port/bowl blended.

I changed to many other things to independently rate the manifold, but everything fit well on it and it looks great.
