There are many different options available for AFR heads, please view the details section below for the details on these heads. Please contact us with questions or check our eBay Store for the many other AFR heads available, and options such as upgrading springs or retainers.

AFR's Coolest Racing Head!
High flowing AFR 227cc intake port small block Chevy angle plug aluminum cylinder heads are available in three stages of performance. The Race Ready version features 100% CNC ported intakes while the higher flowing Competition Package features 100% CNC ported intakes with greater detail. Both come with 100% CNC ported 65cc or 75cc combustion chambers and 80cc exhaust ports with a 3/4" thick head deck (ideal for nitrous or blower applications). In addition AFR also offers the "as cast" Stage 1 heads for 227cc performance on a budget. Standard valves are lightweight 8mm 2.100" intake and 1.600" exhaust with AFR's hardened ductile iron interlocking valve seats. The 227 has 60/40 valve spacing and piston valve pockets should be checked. The exceptional flow characteristics and 23 degree valve angle make this the perfect head for 350 to 434 cid engines in drag cars, sprint cars, and late model oval trackers operating from 4500 rpm and up. The 227cc aluminum cylinder heads are available in either standard or spread port exhaust. AFR offset stud girdles are the only special parts required. Some applications require shaft mount rockers or .050 offset rocker arms for durability and reliability of valve train components. Standard rockers 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 tip. Not recommended for street use, unless a shaft mount rocker system is used. Drilling for centerbolt valve covers available as an option. The exhaust ports are raised .250" over a standard GM L-98 cylinder head. The exhaust ports are raised .250" over a standard GM L-98 cylinder head.

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