AFR 215cc SBC LT1 and LT4 Raised Runner Aluminum Cylinder Heads
|
The Best 23º Cylinder Head You Can Buy
If you must run 23º heads, you just can’t find a better one anywhere!
The unique AFR 215cc Raised Runner small block Chevy cylinder heads
feature a raised intake port to straighten the runner for superior high flow.
These angle plug heads are available in two stages of performance.
With 100% CNC ported intake runners, 76cc combustion chambers and
80cc exhaust ports with a 3/4” thick head deck (ideal for nitrous or blower applications).
We also offer the “as cast” Stage 1 heads for Raised Runner performance on a budget.
Standard valves are 2.100 intake and 1.600 exhaust with AFR’s hardened
ductile iron interlocking valve seats. The incredible flow characteristics,
23º valve angle, and raised runners make this the perfect head for 350 to
434 cid engines in drag cars, sprint cars, and late model oval trackers
operating from 4500 rpm on up. Raised Runner heads are available in either
standard or spread port exhaust. Shaft mount rockers with a 0.450” offset
on the intake are required with a .150” to .180” offset lifter.
The distance from floor to the head deck at the gasket is 0.700”.
Note:
These heads are specifically design for 1992-95 Corvettes and 1993-97 Camaros LT-1 and LT-4
engines using a custom manifold, Super Victor #2926 or sheet metal.
Not available with center bolt valve cover.
