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.

Part came in and work as a champ. Price was better than all other places I look for the set. Will recommended to all my soldiers and/or buddies if they need cylinder heads replace. Thank you guys.

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.

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.
