The Ultimate Bolt-on Emissions Legal Street Weapon The AFR Emissions Legal (versions from 1969-94 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 cylinder heads feature a 65cc or 75cc 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 2.050 (comp package has 2.080) 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 6500rpm, 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 (AFR #1041). Center bolt valve cover is available as a machine option. Exhaust port and bolt pattern are raised 3/32 over GM L98 cylinder heads, this rarely affects header or chassis fitment. Note: 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, with higher spring pressures to reduce chances of valve float associated with rpm 6200 or higher.
