Best prices and customer service on Duramax LML heads out there. Shipped fast and very cool about how long it took to get the cores back.
They supplied me with a perfect set of heads to bring my 1999 Ford Ranger back to life. Ranger Frank has been in the family since the day he rolled off the showroom floor. Its great to have him back on the road.
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.

Premium OEM-Quality Replacement For Restored Engine Performance
This is a professional-grade remanufactured pair of Toyota 4.0L 1GR-FE V6 cylinder heads, including both the left and right sides.

- Pressure Testing: Tested to 60 PSI to ensure no cracks or porosity leaks.
- Surfacing: All heads are resurfaced on our Rottler S85A for a precision gasket-sealing surface.
- Valve Job: Multi-angle valve job performed; every port is Vacuum Tested to ensure valves are seated 100% airtight.
