AFR 210cc SBC LT4 Aluminum Cylinder Heads
|
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 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 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.
Note:
These heads are specifically design for 1992-95 Corvettes and 1993-97
Camaros LT-1 and LT-4 engines using the GM LT-4 or equivalent manifold.
