Product was as described and packaged well! Communication throughout prosses was also great! I will definitely be using them in the future with other projects.
Great company!! The heads arrived in great shape with all the parts. Very quick email responses to questions, comments, and concerns. One little issue with a few parts but was taken care of promply
It's hard to believe no one has reviewed these guys yet. Very professional and detailed company it was a pleasure doing business with you. The answered the phone every time I called or answered every email in a timely manner! I will definitely use them for all my cylinder head needs moving forward. Thank again!
Parts arrived as promised. Ported heads gave me that low end torque and high rev HP I was looking for! ...if only I did the cam at the same time.

Additional Info
New Jeep Dodge Chrysler 3.7L SOHC Cylinder Head (Left Side) – 2002-2013
Restore your engine’s reliability and eliminate the risk of catastrophic failure with our reinforced 3.7L SOHC Left-Side cylinder head, featuring hardened valve seats.
The Chrysler 3.7L PowerTech engine is a workhorse, but it suffers from a critical factory flaw: OEM valve seats that are known to drop out, often destroying the entire engine. Our premium replacement cylinder head is engineered with hardened valve seats to permanently fix this issue. This universal casting is a direct “bolt-on” fit for all 3.7L engines from 2002 to 2013, regardless of whether your vehicle uses an EGR or Non-EGR system.
🛠️ In-House Machining Process
- Debris-Free Preparation: Every new casting is chemically cleaned and blown out to remove all residual machining oils and manufacturing debris, ensuring your oiling system remains uncontaminated.
- In-House Precision Machining: All final machine work is performed in-house, including precision valve seat cutting and guide sizing for perfect geometry and clearances.
- Pressure & Integrity Testing: We pressure-test every head to 60 PSI to verify that the casting is 100% free of porosity leaks or internal defects.
- Dimensional Inspection: Surfaces are verified for perfect flatness, ensuring a flawless gasket seal that meets or exceeds tight OEM tolerances.
- Professional Assembly: Valvetrain components are installed and verified in a clean-room environment. We check spring heights and seal seating to ensure the assembly is ready for immediate use.
- Vacuum-Seal Verification: Every port undergoes Vacuum Testing to guarantee a 100% airtight seal between valves and seats for maximum compression and fuel efficiency.
