RHS is proud of its work on another home-run of an intake manifold. Now available is the 23-degree SBC version, which has optimized air flow and port-matched runners to get everything running smoothly. See more details below.

Official Release:

Take the time-honored Small Block Chevy manifold and completely redesign it for versatility and today’s technology. Sure that sounds cliché, but this new RHS 23-Degree Intake really goes above and beyond.

They started with multiple bolt patterns to fit any Gen 1 head, from classic originals and Vortecs to late model perimeter-styles with vertical bolts. Next they added dual distributor hold downs and threaded water inserts on all four corners for reverse cooling applications. They optimized air flow within and port-matched the runners to match RHS cylinder heads for maximum performance. Available in cast or finished, carb or EFI.

The EFI version is the only one on the market with the injectors angled straight down to the valve stems, and threaded MAP and intake sensor ports in the base. See? We told you it was great.

Features:

• Fits any Gen 1 head
• Available in cast or finished, carb or EFI
