Bought a pair of Remanufactured GM Chevrolet 6.2L Casting #549 Cylinder Head Direct Injection from these guys great product and service.
Best prices and customer service on Duramax LML heads out there. Shipped fast and very cool about how long it took to get the cores back.
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.

Additional Info
Brand New Caterpillar C13 Cylinder Head — Loaded With Inconel Exhaust & 21-4N Stainless Intake Valves
Reinforced Heavy Duty Casting — Built For Reliability, Improved Over OEM
This brand new cylinder head is a direct-fit replacement for Caterpillar C13 diesel engines. Cast from a reinforced heavy duty aftermarket casting and fully assembled with premium Inconel exhaust valves and 21-4N stainless steel intake valves, this head is engineered to outperform and outlast the original. No previous wear history, no patched cracks, no resurfaced gamble — just a stronger, fresh casting ready to drop on and get back to work. This cylinder head fits Caterpillar C13 engines only!
🛠️ Built Stronger Than OEM
- Reinforced Casting: Heavy duty aftermarket casting with added material in high-stress areas to resist the cracking common in high-mileage OEM heads.
- Inconel Exhaust Valves: Nickel-based superalloy exhaust valves withstand extreme exhaust temperatures — stronger and more heat-resistant than standard stainless valves.
- 21-4N Stainless Steel Intake Valves: High-strength austenitic stainless steel for excellent wear resistance and long service life.
- Fully Loaded Assembly: Arrives completely assembled with valves, springs, guides, seats, and seals — ready to install.
- 100% Brand New: Not remanufactured, not rebuilt — a brand new head with zero previous run time.
