Air Flow Research

These reasonably priced AFR 210cc intake port small block Chevy angle plug cylinder heads are available in three stages of performance. The Race Ready version features 70% CNC ported intakes while the higher flowing Competition version features 100% CNC ported intakes. Both come with 100% CNC ported 76cc combustion chambers and 80cc exhaust ports with a 3/4? thick head deck (ideal for nitrous or blower applications). In addition we also offer the ?as cast? Stage 1 heads for 210cc performance on a budget. Standard valves are 2.080 intake and 1.600 exhaust with AFR?s hardened ductile iron interlocking valve seats. The exceptional flow characteristics, 23? 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).The 210cc heads are available in either standard or spread port exhaust. Straight plug versions and down nozzle provisions are special order only. No special parts are required.

Note: Heads are sold as a set. Available with parts ready to install. Please choose in the drop-down menu below. Not for sale or use on pollution controlled vehicles in the U.S.
