Description

The Ferrea F1172P Competition Plus is an exhaust valve designed for SB Chevy engines. It features a 1.625-inch valve head diameter and a 0.3415-inch stem diameter, with an overall length of 5.350 inches.

Constructed with special aerospace quality alloys like EV8-Z18 for high tensile strength, these valves undergo a two-step slow forging process to ensure proper grain flow. They are heat-treated and stress-relieved over a 48-hour period for molecular integrity, and feature avionics-quality hard chrome with a hard tip.
