The "eyebrow" areas under the primaries have been completely removed for maximum flow at wide open throttle. Used one time at Bonneville on my salt flats boattail Riviera - maybe 3 passes total. We have dowel-matched 1" phenolic spacer, also ported, avaiable for extra cost if interested. Located in Carson City, NV, zip=89701. For sale (manifold only) for $265 + shipping. Pictures gladly e-mailed to interested parties (don't know how to post them here)
