Description
The Tillotson Cylinder Head for the 212R and 225R/RS with new EC 5mm Stem Stainless Steel Valves.
This new cylinder head assembly is perfect for many stock appearing classes where you must run 27mm and 25mm valves. Until now, you would need to replace the guides and use 5.5mm guides and valves. That would require more work and more money.
The 5mm valves weigh less than the 5.5mm and more flow potential by reducing obstruction in the bowl area. Using stainless steel vs. stock valves, they can handle bigger and more aggressive cam profiles and run high spring rates.
Our 5mm valves are +.050" Longer. This will change the install height of your spring, therefore, the spring pressure. The extra spring install height will help with higher lift cams requiring more clearance between the retainer and guides and prevent coil bind. If you are running low lift cams, you may need a .050" shim to keep the valve spring rate at the regular install height.
The Head Assembly is for the Cylinder Head and Valves Only. Rocker Assembly, Springs, Push Rod Guide, or Retainers are all sold separately.
