Construction & Design:

Ferrea valves are crafted from premium-grade materials selected for their heat resistance and mechanical strength. The valve stems undergo specialized hardening processes to minimize wear and extend service life, even under the extreme conditions of high-rpm operation. The tulip-shaped valve head design promotes efficient exhaust gas evacuation, reducing backpressure and improving overall engine breathing.

Each valve is precision ground and finished to ensure optimal sealing against the valve seat, which is critical for maintaining compression and preventing leaks. The 22-degree face angle is a hallmark of Ferrea’s engineering, balancing sealing integrity with flow dynamics to maximize combustion efficiency.

Installation & Fitment:

This exhaust valve set is designed for direct fitment in Chrysler HEMI 426 engines requiring +.100" valve jobs. Installation should be performed by experienced engine builders or mechanics familiar with HEMI cylinder head assembly and valve train setup. Proper valve seat machining and valve guide inspection are recommended to ensure optimal valve performance and longevity.

These valves are intended for use in performance or rebuilt engines and may require complementary components such as valve springs and retainers matched to the specific camshaft and operating conditions.
