I haven't. There are no recesses in the flat surfaces of either the barrel or cylinder head and diameter of the hole in the gasket isn't big enough to fit round an o-ring and it definitely shouldn't be pushed inside the hole. Surely it would prevent the head gasket lying flat between the two parts?
I think that's the only place my engine wasn't leaking form and I've taken it apart.

Hi
There's no reason not to do this provided:
The O ring is sized to match the thickness of the head gasket plus compression.
The head gasket hole at this point is corrected for the OD of O ring used.
The O ring is of a material capable of withstanding the heat.
Or it could just be re-built as per design without the additional seal, I'd opt for this.
Regards Mick

Further to my previous post, I've just unearthed another barrel and this one does have a very slight recess round the hole.

No o ring on a 350 that is why it isn't in the parts list
