AFR 195cc SBC Competition Cylinder Head
The AFR Emissions Legal (versions from 1969-94 with heat riser, CARB EO #D-250-2). These heads feature a 74cc combustion chamber with a 64cc exhaust port and a 3/4” thick head deck (ideal for nitrous or blower applications). The exceptional flow characteristics, ideal operating range of 2000 rpm to 6500 rpm, 23º valve angle, and standard valve spacing make this the perfect street head for 350 cid to 400 cid engines from 1955-86. Available for 1987 to present engines with center bolt valve covers and 2 center intake bolts at 72º angle. No special parts are required.
AFR 210cc SBC Competition Cylinder Head
These reasonably priced AFR 210cc intake port small block Chevy angle plug cylinder heads feature 100% CNC ported intakes, and come with 100% CNC ported 66cc combustion chambers and 80cc exhaust ports with a 3/4” thick head deck (ideal for nitrous or blower applications). Standard valves are 2.080 intake and 1.600 exhaust with AFR’s hardened ductile iron interlocking valve seats. The exceptional flow characteristics, 23º valve angle, and standard valve spacing make this the perfect head for 350 to 400 cid engines in bracket drag cars, sportsman oval trackers, and highly modified street class cars operating between 3000 and 7500 rpm (higher rpm ranges possible depending on combination of parts). No special parts are required.
AFR 227cc SBC Competition Cylinder Head
High flowing AFR 227cc intake port small block Chevy angle plug cylinder heads feature 100% CNC ported intakes, with 100% CNC ported 66cc combustion chambers and 80cc exhaust ports with a 3/4” thick head deck (ideal for nitrous or blower applications). Standard valves are 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 23º 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. AFR offset stud girdles are the only special parts required. Some applications require shaft mount rockers for durability and reliability of valve train components. Not recommended for street use, unless shaft mount rocker is used.

AFR 245cc SBC Competition Cylinder Head
245CC NPP (no pushrod pinch) Heads; best suited for max effort applications, but larger displacement 427+ pump gas engines could consider this head as well. This exciting product represents our best flowing 23° SBC head to date and while flow numbers may reflect a very good 18° head of the past, this head is still a conventional direct bolt on non-raised runner intake port configuration. It will drop on your 23° shortblock as easily as our 227 or 235 SBC product and in fact shares indentical valve centerlines and rocker stud locations to both of those heads. However, unlike the 227 and 235 heads, this product will not accept stud mount style rockers and a shaft mount rocker system with the proper intake offset must be used. This is primarily due to the fact we enlarged and widened the pushrod pinch removing that checkpoint in the entrance of the intake allowing us to design a port with a more direct shot at the back of the valve that also has a more consistent cross sectional area and velocity profile. In addition, this head comes standard with a 3/4 inch deck, 2.125 intake and 1.600 exhaust. If you are unsure if this is the right AFR head for you, we encourage you to contact us directly to discuss your combination.
