These reasonably priced AFR 210cc SBC Eliminator racing heads are available in two stages of performance. The race-ready version features 100 percent CNC-ported intakes and 100 percent CNC-ported intakes with greater detail. They come with 100 percent CNC-ported combustion chambers and 80cc exhaust ports with a 3/4 in. thick head deck (ideal for nitrous or blower applications). Standard valves are lightweight 8mm, 2.080 in. intakes and 1.600 in. exhausts with AFR's hardened ductile iron interlocking valve seats. The exceptional flow characteristics, 23 degree valve angle, and standard valve spacing make these the perfect heads for 350 to 400 c.i.d. engines in bracket drag cars, sportsman oval trackers, and highly modified street-class cars operating between 3,000 and 7,500 rpm (higher rpm ranges are possible, depending on the combination of parts). The 210cc aluminum cylinder heads are available for either standard or spread port exhausts.
