2024 Quicksilver® Cylinder Heads

Quicksilver® cylinder heads are ideal replacement components for many GM®-style 4-cylinder and V8 engines in marine, circle track racing, RV, truck and hard-to-find industrial applications. With exclusive Black-X valves, these heads are designed to be the most robust, durable and toughest service cylinder heads available.

Features may include:

• We made the castings thicker, improved the combustion chamber for better burn characteristics, and included premium springs and hardened seats on the intake and exhaust ports for our exclusive Black-X valves.

• The quality of Quicksilver cylinder heads is backed with a one-year limited warranty.

• Black-X composite valves contribute to a 42% reduction in valve wear compared to traditional stainless steel valves with hardened seats, for longer engine life, especially in the presence of modern ethanol-blended fuels.
