Description

28.5mm Stainless Steel Oversize Valves for Ghost 212, Ducar 212, and Tillotson 212E Hemi Cylinder Heads

EC presents the first-ever 28.5mm stainless steel oversize valves specifically engineered for the Ghost 212, Ducar 212, and Tillotson 212E hemi cylinder heads—popular engines in the karting and small engine performance communities.

Designed to enhance durability and performance, these stainless steel valves are lighter and stronger than stock valves, enabling higher valve spring pressures, more aggressive cam profiles, and increased RPM potential. Perfect for racers and enthusiasts looking to upgrade the valve train of their Harbor Freight Ghost 212 or its Ducar and Tillotson counterparts, which share the same hemi head architecture.

Compatibility & Design:
The Ghost 212, Ducar 212, and Tillotson 212E hemi heads use a 5.5mm valve guide and valve stem. The valve tip is undercut to accept 5mm retainers and locks. EC’s stainless steel valves maintain this design to ensure full compatibility with stock retainers and locks. For those upgrading to EC’s lightweight aluminum or titanium retainers, 5mm retainers and locks will be required.

Valve Specifications:

  • Material: High-grade Stainless Steel

  • Valve Weight: 27 grams (same as stock 27mm valve)

  • Head Diameter: 28.5mm (1.123 inches)

  • Valve Face: Dish

  • Margin Thickness: 0.050 inches

  • Overall Length: 3.021 inches

  • Approximate Laid Length: 2.795 inches

  • Tip Length: 0.130 inches (5mm diameter)

Compatible Retainers:

  • EC 267-50 Aluminum Single Spring Retainer

  • EC 268-50 Aluminum Dual Spring Retainer

  • EC 278-50-T2 Titanium Dual Spring Retainer

Upgrade your Ghost 212, Ducar 212, or Tillotson 212E hemi engine with these precision stainless steel oversized valves for improved valve train strength, higher RPM capability, and better overall engine performance.

FAQ

Q1: What engines are these 28.5mm stainless steel valves compatible with?
A1: These valves are designed specifically for the Ghost 212, Ducar 212, and Tillotson 212E hemi cylinder heads, all of which share the same architecture.


Q2: Will these valves fit stock retainers and locks?
A2: Yes, the valves are designed with a 5mm valve tip diameter to work with stock 5mm retainers and locks. If upgrading to EC’s aluminum or titanium retainers, you will need 5mm retainers and locks as well.


Q3: What are the benefits of upgrading to stainless steel valves?
A3: Stainless steel valves are lighter and stronger than stock valves, allowing for higher spring pressures, more aggressive cam profiles, and increased RPM capability, improving overall engine performance and durability.


Q4: Can these valves handle high RPMs and aggressive cams?
A4: Yes, these stainless steel oversize valves are engineered for higher RPMs and more aggressive camshaft profiles, making them ideal for karting and performance engines.


Q5: Do these valves require special installation or modifications?
A5: Yes, the intake seat will need to be cut for the larger 28.5mm valve. They fit directly into the 5.5mm valve guides of compatible engines and use standard retainers and locks unless upgraded.


Q6: What is the weight of these valves compared to stock?
A6: The EC stainless steel valves weigh approximately 27 grams, the same as the stock 27mm valves, but offer improved strength and durability.


Q7: Are these valves suitable for other engines outside Ghost 212, Ducar 212, and Tillotson 212E?
A7: These valves are specifically designed for those three engines due to their unique hemi head design and valve guide specifications. Compatibility with other engines is not guaranteed.
