AFR 220cc SBC Aluminum Cylinder Heads for all Small Block Chevys
|
The Most Popular Racing Head Ever
The powerful AFR 220cc intake port small block Chevy angle plug cylinder heads are available in
three 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.
Both come with 100% CNC ported 76cc combustion chambers and 80cc exhaust ports with a 3/4”
thick head deck (ideal for nitrous or blower applications). In addition we also offer the
“as cast” Stage 1 heads for 220cc performance on a budget. Standard valves are 2.080 intake
and 1.600 exhaust with AFR’s hardened ductile iron interlocking valve seats. The exceptional
flow characteristics, 23º valve angle, and standard valve spacing make this the perfect head
for 350 to 434 cid engines in drag cars, sprint cars, and late model oval trackers operating
between 4500 and 8500 rpm. The 220cc heads are available in either standard or spread port exhaust.
Straight plug versions and down nozzle provisions are special order only. AFR offset stud
girdles are the only special parts required. Some applications require shaft mount rockers
for durability and reliability of valve train components. Not recommended for street use,
unless shaft mount rocker is used.
