Frequently Asked Questions 

How do I know if I have the 4-port or 8-port YD25?
Check your glow plug location. Glow plugs on the passenger side = 4-port. Glow plugs on the driver's side = 8-port. Still unsure? Contact us, and we’ll help you identify the correct head.

Do I need to know my rocker cover type before ordering?
No — our gasket set includes both the alloy and plastic rocker cover gaskets, so you’re covered regardless of which version you have.

Why choose a complete assembled head over a bare casting?
Arrives fully assembled and pressure tested — valves seated, clearances set, camshaft fitted. No machine shop required, saving significant time and labour cost.
