Thanks Guys - yup I think Rudi has hit the nail on the head - water definitely seems to weeping through the casting which suggests cracks and corrosion. The top of the head also looks uneven as though it has been bodged with weld or filler then made pretty with paint - another lesson learnt the hard way.
Guess I'll have to bite the bullet and source a good replacement cylinder head. Trouble is postage to UK is near as dammit twice the price of the head! Have spoken to an agent in UK who can hopefully have one sent over from US with bulk order.
Do we know if new heads are produced in the US or in a back street in Beijing? Is it best to source a good original?
Thanks and will keep you posted. Andy

For sale wanted section of this site. Several folks sell used Cub parts and ship overseas.

Andy:

Sourcing from the US or Canada may not be the only viable method. As you know there are/were lots of Cubs in France -- so there must be boneyards or parts Cubs all over the continent that might have a donor head available. Suggest you search the local forums there . I know Yaume and a few others are on a couple of forums in France and there are a number of Cub owners on those forums. They might be able to help you and keep the shipping costs down. I do know how expensive it is to ship out of the US. That is why a lot of my parts I pick up when I goes statestide. Much cheaper than the postal route.

Bars leak does some good, but if you have nothing to lose, go to your local GM dealer (Vauxhall) and get the GM seal tabs in the parts department (about £3). Crush a couple of those into the top tank and run the tractor normally for a few hours. If it's still leaking, then consider the replace head method.
The head on my '65 loboy has been braze repaired more than once, and still seeps a little, but the GM seal tabs have all but stopped the seeping.
I know all you old timers insist on the head gasket sealers - and I have a mechanic that swears by them, but I've only put them on dry, straight out of the box, and have yet to have one leak....

Thanks for the advice ntrenn (and of course all the others) - an interesting suggestion that I will investigate.
An International parts dealer in UK can supply a new head for £218 plus 20% local tax which equates to about $409 - so when I see them available refurbished at $125 or new at $180 Stateside it is a bitter pill to swallow.
Anyway there is a big show at Scone Palace in Scotland early September featuring Farmall so there might be a few people over from Southern Ireland with interesting bits and bobs. The Cub was imported to Southern Ireland but I am told never officially to UK - so she is quite a rare sight within these shores.
I'll keep you up-dated on progress.
