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.

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

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

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.
