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.
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.
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!
Replacement heads for my 3.5 EcoBoost worked perfect. The kit had everything I needed. The customer service was excellent. Highly recommend this company.
