FR Head Engineering Number - The Ford Focus Forum

**BUR_ZX3** · 03-15-2008, 02:54 PM

I found a head, but I want to confirm the engineering number stamped on it is the appropriate part:

RFYS4E-6090-AD is whats stamped on the head itself. Can anyone confirm that this complies with M-6049-ZX3P.

That sounds like one of the oldler CNC, but it should be okay.... I have to check my notes, I don't have with me right now.

Talked with Randy last night and he seemed to think that they'd all have the same number stamped because they're just original castings of standard Zetec heads that are CNC'd.

But yah Ted if you could find out for me I'd appreciate it.

Yeah, the originals CNC heads just had the standard Zetec number stamped. I believe the new one has a different number.
