Product Description

AFR 190cc Vortec SBC “Eliminator” Street Cylinder Head


The Small Port, High Velocity Torque Monster


AFR 195cc SBC Cylinder Head

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 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 350cid engines from 1996-2000. No special parts are required. Center bolt valve cover is available as a machine option. Exhaust port and bolt pattern are raised 3/32″ over GM L98 Heads, this rarely affects header or chassis fitment.


Hydraulic roller cams typically experience valve float at 6200-6400 rpm because of their fast ramp rates. AFR suggests you upgrade your springs to AFR part #8605, 1.270 O.D. with higher spring pressures and use our Patented “Hydra Rev Kit” to reduce chances of valve float associated with rpm 6200 or higher.
