The Mid-Sized 60/40 Powerhouse!
With the price of big displacement SBC engines fractions 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 the largest direct bolt on 23° Chevy head yet. At 235cc, anything under 400 cubic inches can look the other way. It has the same geometry of the 227 head and will accept all the same rocker arms, stud girdles, shaft mount systems, 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 valve train components. Standard rocker arms can be used but the intake rocker arm will be at a slight angle and the roller tip will not be perfectly centered on the valve. These brand new heads feature a larger 2.125" diameter intake valve. Exhaust valve diameter stays the same at 1.600" with a little more flow from the larger runner volume. The big news is the 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 other companies 18° heads (725+ HP). This head is not for every large displacement combination so if you are unsure whether this is the right AFR head for you, we always encourage you to contact us directly before purchasing. Not recommended for street use, unless a shaft mount rocker system is used. Dual valve cover bolt pattern is standard.
The exhaust ports are raised .250" over a standard GM L-98 cylinder head.

ALL AFR 235cc Competition series available, part numbers 1130-TI, 1132-TI, 1134-TI, 1136-TI

Note:
2.125 valves will require aftermarket pistons notched for valve clearance.
