3VZ Cylinder Head FAQs
Why should I upgrade to LC Engineering's 3VZ cylinder heads?
Upgrading to LC Engineering's 3VZ cylinder heads provides an increase in both performance and durability over stock heads. With improved valve seats, Street Performer valve springs, and a vacuum-tested surface, these heads offer a better seal and smoother airflow for more power and reliability.
What's included in the Pro Cylinder Head Set for the 3VZ V6?
The Pro Cylinder Head Set includes brand new cylinder heads with stock-sized intake and exhaust valves, Street Performer valve springs, hardened keepers, Viton valve seals, and an exhaust stud kit. This set is designed to work with your existing cams and buckets and provides a perfectly flat surface for an optimal head gasket seal.
How do I know if my cylinder head has overheated?
Signs of a cylinder head overheated may include melted heat tabs in the center of the head, visible warping, or recurring cooling system issues like loss of coolant and excessive engine heat. Overheating can damage the valve seats and compromise the head gasket seal, so regular maintenance is essential.
Do I need a valve job on these new 3VZ heads?
No, a valve job isn't necessary as our heads come fully assembled with properly seated valves. Each head is ported and precision-fitted, so you'll have a high-performance option ready for installation without additional modifications.
What is the recommended head gasket for the 3VZ cylinder head?
We recommend using our MLS head gaskets for optimal sealing on our high-performance heads. Our MLS gaskets provide a strong, heat-resistant barrier to handle the demands of a performance engine setup.
