The experience was excellent. My part came sooner than expected and was exactly as advertised. This is how a business should be run. I would give 6 stars if I could, thank you HDPC

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.

Great company!! The heads arrived in great shape with all the parts. Very quick email responses to questions, comments, and concerns. One little issue with a few parts but was taken care of promply
