Bought a pair of Remanufactured GM Chevrolet 6.2L Casting #549 Cylinder Head Direct Injection from these guys great product and service.

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.

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!

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.
