Manley Performance has been manufacturing the finest stainless
steel valves for over 40 years. Manley valves have been the
standard of the industry since their inception; a fact that still
remains true today as weve entered into new markets.
Manley Performance Chevy LS, Ford Modular, and
Chrysler SB HEMI stainless steel valves
utilize our exceptional Race Series alloy and are manufactured to
the highest quality standards.
Manley valves are designed to outflow and outperform all others
even in the most severe environments. Manley stainless valves
feature gorgeous yet durable chrome stems, swirl polished under
heads, fully hardened tips, completely machined combustion faces,
closely controlled margin heights, and exact stem to seat
concentricity to render a finished product that is unsurpassed.
Manley intake valves typically are built with our original
Pro-Flo design which reduces the stem diameter in the fillet area
for increased airflow but also less valve weight. This concept is
executed on our Chevy LS and Chrysler
HEMI parts.
In certain specific applications, Manley offers our Extreme Duty
exhaust material. Our Extremealloy alloy offers more hot hardness
and high temperature strength than our competitors offerings. This
alloy is ideal for extremely high boosted applications where the
exhaust gas temperatures reach what seem like unthinkable levels.
In the case of the Ford Modular 4.6L and 5.4L 3 valve cylinder head
engine, we chose to use Extremealloy.
Manley stainless valves are suitable for all applications
ranging from the mild street performer to the jaw dropping 1000+
horsepower race cars competing at the drag strip.
Manley has been at the forefront with these niche markets;
developing better flowing and stronger aftermarket valves for the
Chevy LS and Ford Modular market before our
competition. We were the first to offer L-92 valves and our hollow
LS valves are the very best in the industry.
