Yes mate they are, the valve springs are single on the 320, and the 325 are double...

Nope, the 320i/323i/325i all use the same double springs.

The 525e engine uses single springs.

Rockers/shafts etc are the same.

In a word,yes..but not much point as the 320 head is reckoned to flow enough air for the engine.You can fit 325 T/B which does help..see Ians guide in the tech help section.Best mod for the 320 is an eta short motor,this works well with a 325 head but do assemble without head bolts first to check that the valves will clear..
