X Series Head Identification

I believe the heads for the x series falcons varied over the range.

I been told that the 87 efi head was the best.. why i dont know, but anywho

What i need to know is when i search the wreckers, how do i tell the difference? The shapes of the chambers and positions of the inlet and exhausts differ, i think?

Any help appreciated, history lesson required maybe.. LOL

Re: X Series Head Identification

be aware that each one almost had a different compression ratio so don't just think you can slap it on any bottom end.

Re: X Series Head Identification

So what sort of engine was in the 89-90 XF Ute? Was this the 3.9 like the EA or the old 250?

late XF ute upto i think early '93 had crossflow '93 dont know month 4.0 came out in XG, there was a '93 ford panel van for 3 grand i looked at a while ago thaat when i looked under the bonnet it still gad a crossflow and 3 speed auto, hence i lost interest real quick.
i'm considering doing a 4.0 conversion to my good XF running straight gas but buying a beat up XG as a donor so i can use power steer,air and radiator stuff that should be a bolt in job
i was told by an engine rconditioner that each crossflow head has different cc in chamber along with dish in pistons varying also between models

um.. not sure if you made a typo but an EF head won't fit an X series crossflow, did you mean XF?

Re: X Series Head Identification

So i should probably steer clear of mixing and matching then..

So anyone got an idea of the best of the X-series donks that i should rebuild
I spose the later models, they will be all efi'd, conversion to carb shouldnt be that hard still.

So any recommended dates of XF that would be best to hot up?
