    The perfect configuration to build a powerful Vortec power and torque!

    The AFR Vortec Emissions Legal (CARB EO #D-250-2), 190cc intake port small block Chevy cylinder heads are available in a straight plug version. They feature a 65cc combustion chamber with a 64cc exhaust port and 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 5500rpm (higher rpm ranges possible depending on combination of parts), 23° valve angle, and standard valve spacing make this the perfect street head for 350ci engines from 1996-2000. No special parts are required. Dual valve cover bolt pattern is standard. Exhaust port and bolt pattern are raised 3/32" over GM L98 Heads, this rarely affects header or chassis fitment. .
