AFR 210cc Eliminator SBC Bare Cylinder Heads, 75cc Chambers, No Parts

The Most Powerful Standard Racing Head Available! - Information below is referring to fully assembled heads.
These reasonably priced AFR 210cc intake port small block Chevy angle plug cylinder heads are available in two stages of performance. 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. Both come with 100% CNC ported 65cc or 75cc 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). The 210cc aluminum cylinder heads are available in either standard or spread port exhaust. No special parts are required. Drilling for centerbolt valve covers available as an option.
The exhaust ports are raised .250" over a standard GM L-98 cylinder head.

Note:
2.080 valves will require aftermarket pistons notched for valve clearance.

Important: Do not port match you intake manifold to any Fel-Pro gasket as it does not precisely match AFR heads.
Note: Milling head deck will affect flow numbers. Angel mills might require .120" thick intake gasket.
