Bob, When I was having head gasket issues a few years back we (Mike Salter
and I) considered using Bar-Leak or similar. I decided to have another go
with an up-market gasket, which did solve my problem, but in talking to Mike
and doing a little research I would have tried Bar-leak with little
hesitation as my next solution. I think the opinions on it blocking water
galleries and rad cores is not based on anything and if it blocked a rad
core I'd day the rad core was almost completely blocked to begin with and
was in need of re-coring. The stuff is not a back-yard solution and I
believe it is a good product.
Just my two cents (based on some research and discussion with people I
trust, not personal experience).
Cheers, Mirek

This may be heresy, but you might want to try one of various 'stop leak/head
gasket sealers' for at least a short term solution. These are usually a
silicate solution that solidifies in cracks; they generally don't work as
well as claimed, but they sometimes work at least a little bit. I've not
known them to block any coolant passages because they don't work THAT well,
and there may not be enough flow in this situation for them to work at all.
My dad worked from the Ford assembly plant that built Mustangs back in the
'60s; he said they threw a bottle of Bars Leaks in every car's radiator. My
engine builder, who worked at Jaguar said they did the same.
This guy at least tries to do 'scientific' comparisons:
