AUTOBABA 5.3L Full Cylinder Head Gasket Kit with ES72220 Bolts for GM 2005–2014 — MLS Gaskets & Complete Seal Set

A complete 5.3L full cylinder head gasket kit from AUTOBABA with ES72220 head bolts and all sealing components needed to rebuild or refresh GM 5.3L V8 engines.

This gasket kit is built for technicians and DIY mechanics replacing head gaskets or performing top-end engine work on 5.3L GM Vortec engines used across many Buick, Chevy, GMC and compatible models from roughly 2005–2014. The package groups multi-layer steel head gaskets with 30 ES72220 head bolts and a broad assortment of gaskets, seals, o-rings and valve stem seals so you can complete a head service without sourcing separate parts.

What parts come in the kit and why are they included?

The kit bundles everything typically required for a full cylinder head service: MLS head gaskets, head bolts, intake and exhaust gaskets, valley cover and oil pan gaskets, crank seals, valve stem seals and assorted o-rings and plates. These parts ensure all common sealing surfaces are replaced to reduce future leaks after disassembly.

• Multi-layer steel head gaskets sized for 5.3L combustion bores
• 30 ES72220 cylinder head bolts specified for GM 5.3L torque patterns
• Oil pan, valley cover, intake and exhaust gaskets included
• Rear crankshaft seals, valve stem seals, grommets and damping plugs

Which vehicles and engines does this AUTOBABA kit fit?

How does this kit support a reliable head gasket repair?

By replacing all critical seals and fasteners at once, the kit helps restore proper sealing surfaces and correct clamping force across the heads. Using MLS gaskets and correct-spec head bolts reduces the chance of rework caused by reused or degraded parts.

• MLS head gaskets tolerate high combustion pressures and temperature cycles
• New ES72220 bolts provide correct stretch and torque retention
• Complete gasket coverage prevents oil and coolant migration after assembly
• Includes small seals and grommets often overlooked but vital to leak-free results
