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
Replacement heads for my 3.5 EcoBoost worked perfect. The kit had everything I needed. The customer service was excellent. Highly recommend this company.
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.
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!
