With the price of big displacement SBC engines fraction of what they were years ago, the allure to go BIG is stronger than ever. To help quench the thirst of that large displacement monster AFR is proud to offer our largest direct bolt on 23° Chevy head yet. At 235 cc’s, anything under 400 inches can look the other way. It has the same geometry as our 227 head and will accept all the same rocker arms, stud girdles, etc. AFR offset stud girdles are the only special parts required (see footnotes here). Some applications require shaft mount rockers or .050 offset intake rocker arm for durability and reliability of valve train components. With the .050 offset the intake rocker arm will be at a slight angle and the roller tip will not be perfectly parallel or centered on the valve. It will feature a larger 2.125 diameter intake valve. Exhaust valve diameter stays the same with a little more flow from its larger runner volume. The big news is our all new intake port design which pushes this standard location intake port over 340 CFM’s! That’s 18° territory and this head should be able to generate power figures that rival those heads (725+ HP). As well the exhaust port is raised .250 over GM L98 head. This head is not for every large displacement combination so if you’re unsure whether this is the right AFR head for you, we always encourage you to contact us directly.
