I currently have three pairs of iron closed-chamber cylinder heads. Two pairs are bare cylinder heads. All three pairs are for sale.
One pair is complete and freshly rebuilt with no miles, but from what I can tell it was not a performance rebuild.
I was told one of the bare pairs is the desirable Australian closed-chamber heads.
If that is true then one of the two versions in this photograph would be Australian. I see distinct differences in the spark plug areas.
Can anyone tell from this photo, or provide other clues for me to check?
Thanks in advance,
