Description
This listing is for a remanufactured cylinder head compatible with GM 4.8 L and 5.3 L engines — casting number 862 (common on older Chevy / GM V8 engines). This head is rebuilt to OEM-level standards, restoring proper sealing, compression, and reliability. It’s ideal for replacing a cracked, warped or worn head, or when doing a full engine rebuild for long-term performance.
Rebuild Process & Quality Assurance
-
Full disassembly and cleaning via hot-tank (or equivalent), removing all carbon, deposits, and old gasket residue.
-
Casting is pressure tested to ensure integrity — checking for cracks, porosity, or other defects before reassembly.
-
All valve stem seals replaced; any worn valve guides replaced as needed to restore proper valve sealing and alignment.
-
Precision multi-angle valve job performed; valves are checked and seated properly to ensure proper compression and smooth operation.
-
Deck surface machined to flat, factory-spec finish to ensure proper head-gasket sealing and prevent leaks.
-
Final cleaning, inspection, measurement, and re-assembly under strict quality control — delivering a cylinder head that’s ready to install with confidence.
