The Small Port, High Velocity, Torque Monster!

The AFR Emissions Legal (CARB EO #D-250-2 for engines up to 1994), 180cc intake port LT1 Small Block Chevy cylinder heads are available in the LT1 angle plug version only. These heads feature a 55cc to 65cc 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 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 6000 rpm (higher rpm ranges possible depending on combination of parts), 23° valve angle, and standard valve spacing make this the perfect street cylinder head for 350-383ci performance engines and is specifically designed for 1992-95 Corvettes and 1993-97 Camaros. No special parts are required (see footnotes here). Dual valve cover bolt pattern is standard. Exhaust port and bolt pattern are raised 3/32" over GM L98 cylinder heads, this rarely affects header or chassis fitment. .
Installation Note: Hydraulic roller cams typically experience valve float at 6200-6400 rpm because of their fast ramp rates. AFR suggest you upgrade your springs to AFR part number 033-8605, 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.
