Description
Powerful and Proven Standard Valve and Stud Racing Head! - Information below is referring to fully assembled heads.
These reasonably priced AFR LT4 210cc cylinder heads in the Race Ready version features 100% CNC ported intakes while the higher flowing Competition version features 100% CNC ported intakes with greater detail and higher flowing exhaust ports as well. Also features 100% CNC ported 55cc-65cc combustion chambers and 80cc exhaust ports with a 3/4" thick head deck (ideal for nitrous or blower applications). Standard valves are lightweight 8mm 2.080" intake and 1.600" exhaust with AFR's hardened ductile iron interlocking valve seats. The exceptional flow characteristics, 23° valve angle, and standard valve spacing make this the perfect head for 350 to 400 cid engines in bracket drag cars, sportsman oval trackers, and highly modified street class cars operating between 3000 and 7500 rpm (higher rpm ranges possible depending on combination of parts). No special parts are required, besides the LT4 intake manifold. Dual valve cover bolt pattern is standard.
The exhaust ports are raised .250" over a standard GM L-98 cylinder head.
