What material are these exhaust valves made from?

These COMP Cams exhaust valves are made from stainless steel. This material is chosen for its ability to withstand the high temperatures and stresses encountered in the exhaust side of an engine, contributing to their durability.

Are these valves a direct replacement for my LS engine?

Yes, these valves are designed as a direct fit for many GM LS engines with a 1.570-inch head diameter and 5.450-inch length, featuring an 8mm stem. They are intended to work with the factory valve train components.

What is the benefit of stainless steel for exhaust valves?

Stainless steel offers better resistance to heat and corrosion compared to some other metals. This makes it a suitable material for exhaust valves, which operate under extreme thermal conditions, potentially leading to a longer lifespan for the component.
