Performance Head Gasket Kit & Seals for Ford F-350 (2007-2010) 5.4L

Heavy-Duty Performance Full Engine Head Gasket Kit for 2007-2010 Ford F-350 (P356)

What it Does: The Performance Head Gasket Kit seals the combustion chambers and internal fluid galleries on the 2007-2010 Ford F-350 to prevent cylinder pressure blow-by, coolant migration, and external oil leaks under heavy commercial workloads.

The Stock Ford F-350 Head Gasket & Seal Degradation

Under heavy towing and prolonged thermal loading, the factory 5.4L Triton 3V engine in the P356 chassis suffers from severe deck temperature cycling. Differential thermal expansion between the cast iron engine block and aluminum cylinder heads causes localized micro-fretting against standard seals. Over extended heat cycles, factory head gaskets lose clamping torque tension, allowing combustion pressure to breach coolant jackets. Secondary weaknesses include dry-rotted valve stem seals leading to oil consumption, brittle exhaust manifold gaskets that blow out under backpressure, and deteriorated front and rear crankshaft seals that weep oil under high crankcase pressures.

The Engineering Solution

This full engine overhaul gasket kit restores complete hermetic sealing across the entire Modular V8 architecture. The multi-layer steel (MLS) head gaskets feature high-tensile spring steel layers with proprietary combustion fire rings designed to absorb thermal shear and cylinder head lift. High-durometer fluoroelastomer (FKM) valve stem seals withstand extreme exhaust gas temperatures without hardening, while reinforced multi-port intake and exhaust manifold gaskets maintain uniform sealing under severe duty cycles. Complete lower-end and timing gaskets ensure positive crankcase sealing to withstand high-mileage fleet service.

Frequently Asked Questions & Fitment Warnings

Does this fit the P356 F-350?

Yes, this is a direct fit for the 2007-2010 Ford F-350 equipped with the 5.4L Triton SOHC 24V engine. Confirm your vehicle displacement and VIN engine code prior to ordering; this kit does not fit 6.8L V10 or Power Stroke diesel platforms.

Can the factory cylinder head bolts be reused with this gasket kit?

No, the factory fasteners on the 5.4L Triton are torque-to-yield (TTY) bolts that permanently stretch during installation and must be replaced with new hardware or high-tensile head studs.
