AFR 235 Eliminator SB Chevrolet Cylinder Heads - (80cc)
Our Mid-Sized 60/40 Valve Spaced Powerhouse
With the price to build big displacement small block Chevrolet engines fraction of what they were years ago, the allure to go BIGGER is stronger than ever. To help quench the thirst of that large displacement monster, AFR is proud to offer another large port direct bolt on 23° Chevy head. Identical valvetrain 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. Some applications require shaft mount rockers or .050" offset intake rocker arm for durability and reliability of valvetrain components. Due to 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.
The 235 heads feature a larger 2.125" diameter intake valve than the 227 heads. Exhaust valve diameter remains the same at 1.600" with a little more flow from its larger runner volume. As well the exhaust port is raised .250" over factory GM L98 head. The big news is the all new intake port design which pushes this standard location intake port over 340 CFM. That’s 18° territory and this head should be able to generate power figures that rival those heads (725+ HP).
