Manley Titanium Exhaust Valve Kit - Small Block GM, Ford, Chrysler

Starting with a 1.625-inch head diameter and a 0.3415-inch stem, these Manley titanium exhaust valves are crafted from exceptional titanium alloys. This material choice is key for reducing valve train weight, which directly helps your engine perform better, especially when you're pushing it to higher engine speeds. The goal here is to make your engine more efficient and capable of handling those demanding high-rpm applications.

Manley builds these valves using a one-piece forged construction, which means the grain flows properly through the entire piece. This makes them more durable and less likely to have weak spots compared to valves that are welded together. They're then precisely machined on advanced CNC equipment to ensure they meet very exact tolerances. The titanium alloys used are chosen to balance strength, hardness, and flexibility at the high temperatures found in an engine, and the 'HT' suffix means they're made with high-temperature material. Plus, they come with inserted hard tips for added durability.

This kit includes a set of 8 valves, each weighing in at just 77 grams, and they are designed with a groove for bead lock. Manley puts each valve through a strict final inspection to make sure you're getting a reliable part that performs as expected. These valves are a solid option if you're building an engine for serious performance and need to shave weight from the valvetrain for improved responsiveness and higher rev limits.
