Description

Tillotson 225RS CNC-Ported Cylinder Head – Ported by EC Carburetors


Unlock more power from your 225RS engine with this CNC-ported Tillotson 225RS Cylinder Head, expertly modified by EC Carburetors. Built for racers looking to get the most out of evolving track rules, this high-performance cylinder head retains the stock 27mm intake and 25mm exhaust valves, along with stock retainers and 26 lb valve springs — but gains a serious edge through precision CNC porting and a decked surface for increased compression.


As some tracks and racing series begin allowing ported heads with the introduction of the new header and 7500 RPM-limited coils, this head provides the perfect balance of rule-compliant upgrades and reliable power gains. Whether you're building for performance within valve size restrictions or just looking for an edge in open classes, this head is race-ready and track-proven.


Key Features:

- CNC-Ported for Maximum Flow – Optimized intake and exhaust ports increase airflow and improve combustion efficiency

- Stock Valve Configuration – 27mm intake & 25mm exhaust valves to meet common spec class requirements

- Upgraded Valve Springs – Equipped with 26 lb springs for improved high-RPM durability

- Decked for Higher Compression – Increases cylinder pressure for more power and throttle response

- Race-Legal Performance – Ideal for classes that allow porting but require stock valve sizes (check your local rules)

- Built by EC Carburetors – Precision-machined in-house by one of the most trusted names in small engine performance


Note: Always verify your local track or series rules before purchasing, as cylinder head porting may or may not be allowed in your class.
