AFR 210cc Competition Eliminator SBC Bare Cylinder Heads, Spread Port, 65cc Chambers, No Parts

AFR 1106NP
Spread port heads have the center exhaust ports spread apart approximately 1/2" over stock GM heads. The reason for spread port heads is to achieve additional cooling in the center of the head where the heat concentration is greatest. As standard headers do not fit, spread port headers are required since the center ports are spread further apart than stock GM products. The increased spacing on the exhaust port also requires the use of exhaust gasket Fel-Pro #1409. Spread port heads only come with a Stahl bolt pattern. AFR's spread port head has all the benefits and features of AFR's standard head. As all benefits and features are the same, please review respective page for product details (i.e. for 210cc spread port view 210cc SBC "Eliminator").

Note: Head comes completely bare, no parts.

*Notice Pictures are for reference heads would come bare, no parts.

Description

The Coolest Standard Racing Head Available! - Information below is referring to fully assembled heads.
These Spread Port 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.
