    The Small Port, High Velocity, Torque Monster!

    This Emissions Legal 180cc intake port small block Chevy eliminator cylinder head is available in your choice of straight or L98 angle plug versions and they are CARB certified EO #D-250-2 (versions from 1969-94 with heat riser). These performance heads feature a 75cc or 65cc combustion chamber with a 64cc exhaust port and a 3/4'' thick head deck (ideal for nitrous or blower applications.) Standard valves are lightweight 8mm diameter stem, 2.020'' intake and 1.600'' exhaust with AFR's hardened ductile iron interlocking valve seats. The exceptional flow characteristics, ideal operating range of idle to 5500 rpm (higher rpm ranges possible depending on combination of parts), 23° valve angle, and standard valve spacing make this the perfect street aluminum cylinder head for 327-350ci engines from 1955-86. Also available for 1987 to 1995 cast iron head engines with center bolt valve covers and 2 center intake bolts at 72° angle, AFR head p/n 033-919. No special parts are required. Dual valve cover bolt pattern is standard. Exhaust port and bolt pattern are raised 3/32'' over GM L98 cylinder heads, this rarely affects header or chassis fitment. Made in USA.
