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.
