Description

This listing is for remanufactured cylinder heads compatible with the 3.3 L V6 3MZ-FE engine. This engine was used in a variety of Toyota (and some Lexus) vehicles — including but not limited to Camry, Sienna, Highlander, and other models — from the early 2000s onward.

The heads are rebuilt to OEM-level standards, aiming to restore proper compression, sealing, and smooth V6 operation — especially useful when the original heads are damaged, warped, or leaking.

Rebuild Process & Quality Assurance

Full disassembly and thorough cleaning (hot-tank or equivalent) to remove carbon, oil deposits, and old gasket residues, preparing the casting for inspection and rebuild.
Pressure testing of the casting to confirm structural integrity — ensures no cracks or defects before reassembly.
New valve stem seals installed on all valves; worn valve guides replaced as needed to ensure proper valve seating and reliable long-term sealing.
Precision valve seat work / multi-angle valve job to restore proper sealing, compression, and valve flow characteristics.
Deck surface resurfaced (milled) to a flat, smooth finish suitable for proper head-gasket sealing and engine reliability.
Final cleaning, inspection, measurement, and reassembly under strict quality standards — resulting in a rebuild-complete cylinder head ready for installation.

Fitment / Applications

These cylinder heads are designed for vehicles equipped with the 3.3 L 3MZ-FE V6 engine, including but not limited to:

Toyota Camry (when equipped with 3.3 L 3MZ-FE)
Toyota Sienna (3.3 L V6)
Toyota Highlander (and Highlander Hybrid, 3.3 L versions)
Some Lexus vehicles that use 3MZ-FE / related engine variants (depending on year and configuration)

Before purchase, buyers should verify:

That their engine is 3MZ-FE (check engine code / VIN / casting)
Bolt-hole pattern, port layout, and head-gasket surface match their block
Intake/exhaust manifold, coolant and oil passage alignment, and valve-train compatibility

Shipping & Handling

Shipped via standard carrier with tracking. Cylinder heads are carefully packaged to protect machined deck surfaces, valve seats, and internal oil/coolant passages during transit.

Fitment Disclaimer

Buyer is responsible for verifying that the cylinder heads match their engine before installation. Please confirm engine code (3MZ-FE), block compatibility, casting identifier, and gasket / port alignment prior to install.
