3078380 Cummins N14 Cylinder Head Stage 1 Regular Intake & Exhaust Valves

Benefits of JAK's Diesel Performance Cylinder Head

Brand new, fully assembled performance cylinder head compatible with Cummins N14 engines. Our castings are proudly engineered, designed, and built in the USA. They exceed standard quality with 5% higher nickel content in the material, which strengthens the head and helps prevent cracks between valve seats.

We've also increased coolant passage size by 30% and added reinforced internal ribs to better manage heat and reduce thermal stress. If you've dealt with a cracked cylinder head before, you know the downtime and expense involved. Avoid risking a repeat failure with a basic remanufactured unit—upgrade to JAK's Diesel Enhanced Performance Cylinder Head for reliable, worry-free operation on long hauls!

What Makes This Enhanced Performance Cylinder Head Special?

This is a true performance upgrade over a standard cylinder head. If you're pushing your engine harder for more power and want protection against corrosion, pitting, or cracking, this is the ideal cylinder head upgrade!
