Description

24mm Stainless Steel Exhaust Valve – Ghost 212, Ducar 212, Tillotson 212E Hemi


Upgrade your hemi cylinder head with EC’s 24mm Stainless Steel Exhaust Valve—engineered for performance, strength, and reliability. Designed specifically for the Ghost 212, Ducar 212, and Tillotson 212E Hemi engines, this valve is the first of its kind in stainless steel, offering enhanced durability and improved valve train performance for racing and high-RPM applications.


Crafted from lightweight stainless steel, the EC 24mm exhaust valve is 3 grams lighter than stock, helping reduce valve train mass. This allows you to safely run higher spring pressures, more aggressive camshafts, and higher RPMs with confidence. Whether you're upgrading a racing kart, mini bike, or small block build, this is the performance solution trusted by top builders.


Like the OEM valves, these are designed with a 5.5mm stem diameter and undercut tip to accommodate stock 5mm retainers and locks. Optional EC aluminum or titanium retainers can be used for further gains in performance.

FAQ

Q1: Will this 24mm valve fit a Predator 212 non-hemi engine?
A: No, this valve is specifically designed for Hemi-style cylinder heads found in the Ghost 212, Ducar 212, and Tillotson 212E. It will not fit Predator 212 non-hemi models.


Q2: Can I use the stock retainers and locks with this valve?
A: Yes. EC’s stainless steel valve is undercut to use 5mm retainers and locks, just like the stock valve. However, for enhanced performance, you can also upgrade to EC’s aluminum or titanium retainers.


Q3: What is the benefit of using a stainless steel exhaust valve?
A: Stainless steel offers greater strength and heat resistance than stock materials. It’s also lighter, which reduces valve train mass, allowing higher RPM operation and improved cam and spring compatibility.


Q4: Does this valve require any modification to install?
A: In most cases, no modifications are needed as long as it’s installed in a compatible Hemi head (Ghost 212, Ducar 212, Tillotson 212E). Always check valve clearance and spring specs before final installation.


Q5: How does this valve improve engine performance?
A: It’s lighter weight and stronger construction help reduce valve float, allow for higher spring pressure, and maintain durability under higher RPM—ideal for performance and racing applications.
