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
Bought a pair of Remanufactured GM Chevrolet 6.2L Casting #549 Cylinder Head Direct Injection from these guys great product and service.
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.
I got my cylinder head quicker than expected. I would buy from this company again
