GEN1 2011-2016 3.5L EcoBoost F-150 EMS Built Heads

These are fully rebuilt and upgraded cylinder heads for the 2011–2016 Ford F-150 with the 3.5L EcoBoost engine (GEN1). They’ve been carefully prepared in-house by our team at EMS to give your truck better performance and long-term reliability.

What’s Been Done:

• ✔️ Brand-new Kelford valve springs installed for better strength and durability

• ✔️ Professional valve job for a cleaner, tighter seal

• ✔️ O-ringed and prepped for copper head gaskets to prevent leaks

• ✔️ Light porting behind the valves to help airflow and efficiency

• ✔️ Cleaned, inspected, and assembled — ready to bolt on

These heads are a great choice if you’re rebuilding your engine or looking to upgrade without starting from scratch.
