AFR 195cc SBC Eliminator Street Cylinder Head

The Ultimate Bolt-on Emissions Legal Street Weapon

AFR 195 SBC Cylinder HeadThe 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 6500 rpm, 23º 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 72º angle. No special parts are required (see footnotes here). Dual valve cover bolt pattern is standard. Exhaust port is raised .100 over GM L98 cylinder heads.

Note:

Hydraulic roller cams typically experience valve float at 6000-6200 rpm because of their fast ramp rates. AFR suggest you upgrade your springs to AFR part #8047, 1.290 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.
