Hello everyone. I have a 2002 Ford fiesta 1.6 RSi that I'd like to do some work on, particularly regarding the cylinder head. The car has a 1.6l SOHC 8V Rocam engine. I believe it's the same engine as the 1.6 XLT Ford Bantam. I would like to know if the cylinder head from the Zetec S of the same generation is interchangeable with the one on my RSi.
