High-Performance Exhaust Valves – Alfa Romeo 1600 Nord – Motorsport Specification

Description

Technical Product Description:

These high-performance inlet valves are specifically designed for the Alfa Romeo 1600 Nord engine, delivering superior airflow, strength, and durability under extreme operating conditions.

Developed for competition and high-performance street applications, these valves feature a revised seat angle geometry — transitioning from the standard 30° seat angle to a 45° seat angle — significantly improving airflow through the intake ports. This modification enhances volumetric efficiency, particularly at mid-to-high RPM, resulting in increased engine breathing capacity and performance.

Key Features:

• Motorsport-grade inlet valves for Alfa Romeo 1600 Nord Engines.
• Upgraded seat angle: 45° (from OEM 30°) to maximize airflow and improve intake efficiency
• Forged from high-strength stainless steel alloys for excellent heat and fatigue resistance
• Optimized valve head and stem profiles for enhanced gas flow dynamics
• CNC-machined for consistent tolerances and precision seating
• Hardened valve tips for increased durability in high-load applications
• Compatible with high-lift camshafts and stronger valve springs
• Suitable for both naturally aspirated and turbocharged engines operating at high RPM

Recommended for: Track, rally, and performance street engines requiring improved intake airflow, increased valve strength, and optimal high-RPM reliability in Alfa Romeo 1600 Nord applications.

Note: Professional installation is strongly recommended. Verify piston-to-valve clearance and camshaft compatibility before use.
