Hello all,

I've picked up a used 2.0 Zetec cylinder head that the previous owner claims was reworked by Dunnell.

Does anyone know if Dunnell marks the heads they've ported in any way, so I can verify the story?

yeah there is usually teaped numbers on the end near thermo housing? valves may be modded also. Is there cams aswell??

 

There were no valves or cams with the head. On the thermo end, I only found a "1" and an "A" in two separate spots.

 

Mine has an rmpxxx number stamped in. Is it nicely ported ?

 

It is. Not wildly, but you can see there was thought put into it, not just "how big can I make this hole!"

Well, I guess the dyno will tell me if this was a smart purchase, even if I can't validate that Dunnell is who ported it.
