These reasonably priced AFR 210cc intake port small block Chevy LT4 angle plug, reverse cooled cylinder heads are available in two stages of performance. The Race Ready version features 100% CNC ported intakes while the higher flowing Competition version features 100% CNC ported intakes with greater detail. Both come with 100% CNC ported 58cc combustion chambers (can be special ordered 55 to 65cc) and 80cc exhaust ports with a 3/4'' thick head deck (ideal for nitrous or blower applications). Standard valves are lightweight 8mm diameter stem, 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 350-400ci engines in bracket drag cars, sportsman oval track racers, 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. Dual valve cover bolt pattern is standard. Exhaust port and bolt pattern are raised .250'' (1/4'') over GM L98 cyilnder heads, this rarely affects header or chassis fitment. Made in USA.
