4. Installation Instructions
Professional installation is recommended. Always refer to your vehicle's specific service manual for torque specifications and detailed procedures. The following steps provide a general overview.
4.1. Preparation
- Ensure the engine is cool and disconnected from the battery.
- Drain engine oil and coolant.
- Remove all necessary components to access the cylinder heads and lifters (e.g., intake manifold, valve covers, rocker arms, pushrods).
- Clean all mating surfaces thoroughly to ensure proper sealing.
4.2. Lifter Pre-Lubrication
Before installation, it is crucial to lubricate the new hydraulic roller lifters to prevent dry start damage.
- Submerge the lifters in clean engine oil for 10-15 minutes. This ensures all internal parts, including springs and rollers, are well-lubricated.

4.3. Camshaft Installation
If replacing the camshaft, ensure it is adequately lubricated before insertion into the engine block.
- Apply a generous amount of assembly lube (e.g., Lucas High Performance Assembly Lube) to the camshaft lobes and journals.
- Carefully slide the camshaft into the engine block, ensuring it does not bind or damage the bearings.

4.4. Lifter Installation
- Carefully insert the pre-lubricated lifters into their respective bores in the engine block.
- Install the lifter guides to hold the lifters in place.

4.5. Gasket and Bolt Installation
- Place the new head gaskets onto the engine block, ensuring correct orientation.
- Install the cylinder heads and secure them with the new cylinder head bolts. Follow the manufacturer's specified torque sequence and values.
- Install the intake manifold gasket, exhaust manifold gaskets, valve cover gaskets, and other seals as required.
4.6. Reassembly and Fluid Refill
- Reinstall all removed components in reverse order.
- Refill the engine with the appropriate type and amount of engine oil and coolant.
- Reconnect the battery.
