What type of valve locks are needed for these retainers?

These Manley retainers require specific 7-degree valve locks. The manufacturer recommends using Manley Valve Lock P/N 13091, which are designed for LT-1, LT-4, and L-98 Gen I/II SBC engines.

What is the main benefit of using titanium retainers?

The primary advantage of titanium retainers is their reduced weight compared to steel. This lower mass in the valvetrain allows the engine to achieve higher RPMs more safely and reliably.

What does the '+.050 inch install height' specification mean?

This refers to the installed height of the valve spring assembly. The +.050 inch specification indicates that the retainer is designed to achieve this specific measurement when installed with the appropriate valve spring and locks on your engine.

About this part

Product Details

Starting with a specific material choice, these Manley valve spring retainers are made from 6AL-4V titanium, chosen for its excellent strength-to-weight ratio. This material helps reduce the overall mass in your valvetrain, which is a key factor in allowing your engine to safely reach higher RPMs. They are CNC machined to tight specifications, ensuring they work precisely with your valve springs and locks.

The design focuses on shedding weight without compromising the strength needed to keep your valves under control, especially when you're pushing your engine hard. You'll need to use specific 7-degree valve locks, like the Manley P/N 13091, which are designed for this retainer and the LT1/LT4/L98 engine families. The retainer is set up for a +.050 inch install height, which is a common specification for many performance builds.
