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.

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

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.

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
