you seem to have missed the point, same casting would do a 9 or 10 stud barrel just drilling as necessary.
If their is any other difference its probably internal
No, since reading around somewhat you are correct in that the same casting appears to have been used for both. 10th hole cast-plugged for the then 120, drilled open for the 140. What I was getting at is that this head is different to the head used for a 66 120 - slightly larger exhaust vv head, stellite tipped vvs and possibly slightly different compression. Considering I have what appears to be the correct barrel, does this give rise to concern? I would have thought not......
No leaks anywhere, and I have no issues with the guy who did the rebuild.
