AFR 210cc SBC Racing Cylinder Head
The Most Powerful Standard Racing Head Available
|
|
These
reasonably priced AFR 210cc intake port small block Chevy angle
plug cylinder heads are available in three stages of performance.
The Race Ready version features 70% CNC ported intakes while the
higher flowing Competition version features 100% CNC ported intakes.
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 210cc 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 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 heads are available in either standard or spread
port exhaust. Straight plug versions and down nozzle provisions
are special order only. No special parts are required.
