Model Number: 1036
Air Flow Research

The AFR Emissions Legal (versions from 82-92 with heat riser, CARB EO #D-250-2), 195cc intake port small block Chevy cylinder heads are available in your choice of straight or L98 angle plug versions. These heads feature a 74cc or 68cc combustion chamber with a 64cc exhaust port and a 3/4? thick head deck (ideal for nitrous or blower applications). The 68cc chambers are designed for flat top or dished pistons; domed pistons will require additional machining. Standard valves are 2.020 intake and 1.600 exhaust with AFR?s hardened ductile iron interlocking valve seats. The exceptional flow characteristics, ideal operating range of 2000 rpm to 6500 rpm, 23? valve angle, and standard valve spacing make this the perfect street head for 350 cid to 400 cid engines from 1955-86. Available for 1987 to present engines with center bolt valve covers and 2 center intake bolts at 72? angle. No special parts are required.

Note: Hydraulic roller cams typically experience valve float at 5800-6000 rpm because of their fast ramp rates. AFR suggest you upgrade your springs to AFR part #8032, 1.530 O.D. with higher spring pressures and use our Patented ?Hydra Rev Kit? to reduce chances of valve float associated with rpm 6000 or higher.

Note: Heads are sold as a set. Available with parts ready to install. Please choose in the drop-down menu below. All of the heads listed here are emissions legal in all 50 states.
