CYLINDER HEADS

The Lungs of Your Engine: Maximum Airflow and Cooling Performance

In an air-cooled engine, the cylinder heads are arguably the most critical component for determining both power output and engine longevity. They act as the "lungs" of your Volkswagen, responsible for the intake of fuel and air and the efficient expulsion of exhaust gases. More importantly, they are the primary heat exchangers for your engine. At Appletree Automotive, we provide the high-performance and stock-replacement cylinder heads needed to keep your Beetle, Bus, or Sand Rail running strong and staying cool.

Whether you are looking for the original reliability of a single-port head or the massive airflow of a CNC-ported 044 race head, we have the specialized hardware your build demands.

Why Shop Cylinder Heads at Appletree Automotive?

• Performance Dual-Port Upgrades: Unlock significant horsepower gains with our selection of dual-port cylinder heads. Designed for improved volumetric efficiency, these heads are the foundation for any performance-oriented Type 1 or Type 4 engine build.

• Big Valve & High-Flow Technology: For high-displacement stroker engines and turbocharged applications, we offer cylinder heads with oversized stainless steel valves and optimized port shapes. These features maximize airflow at high RPMs, ensuring your engine never "gasps" for air.

• Advanced Cooling Castings: Heat is the enemy of the air-cooled head. Our performance heads feature reinforced castings and improved fin designs to shed heat faster, preventing the "dropped valve seats" and cracks often associated with inferior or worn-out factory heads.

• Off-Road and Racing Durability: Dune buggies and sand rails operate under extreme loads and high temperatures. We carry heavy-duty heads specifically engineered for off-road use, featuring long-reach spark plug bosses and high-strength valve train components that can take a beating in the dunes.

• Precision Machining & Fitment: We stock heads "cut" for various bore sizes, including 90.5mm, 92mm, and 94mm, ensuring a perfect seal and correct compression ratio for your specific cylinder combination.

• The Appletree Advantage: Selecting the right combustion chamber volume and valve size is a technical process. Our experts are here to help you match your heads to your camshaft and displacement to ensure a balanced, high-performing engine.

• Free Shipping on Orders Over $75: Investing in your engine's top end shouldn't be weighed down by shipping costs. Take advantage of our free shipping offer on qualifying orders over $75 to get your performance cylinder heads delivered directly to your workshop.
