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!
They supplied me with a perfect set of heads to bring my 1999 Ford Ranger back to life. Ranger Frank has been in the family since the day he rolled off the showroom floor. Its great to have him back on the road.
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.

š ļø In-House Machining Process
- Debris-Free Preparation: Every new casting is chemically cleaned and blown out to remove all residual machining oils, metal shavings, and manufacturing debris. This ensures your oiling system remains uncontaminated from the first start-up.
- In-House Precision Machining: Unlike “shelf-stock” parts, we perform final inspections and precision verification in-house. This ensures perfect geometry and clearances before the crankshaft reaches your engine block.
- Dimensional Inspection: Our technicians perform a multi-point inspection of the journals and snout alignment. This ensures the crankshaft meets tight OEM and performance tolerances for a flawless fit.
- Balance Verification: Every crankshaft is verified for internal balance, reducing engine vibration and ensuring smooth operation even at higher RPMs.
- Surface Integrity Testing: We verify that the casting is free of porosity or internal defects that could compromise the strength of the journals under high-stress driving conditions.
