Thanks to those that made comments about repairing the o-ring

use the core for a mock up, and spare parts.  The stage that I

am at

now

gives me a few more years to get everything ready.  The intake

another

one of the big Questions that I have.  I don't understand the

enough to

Usually cooling fluid is found in the combustion chamber.

I too have lived thru this failure.  My worst symptom was that the
combustion gases over pressurized the coolant system and caused the
coolant to overflow and the car would overheat.  I repaired the end
housing by brazing a small piece of steel next to the oring slot and
filing the repaired area flat with a file (Tracy Crook's suggestion on
how to make the repair).  I know that the repair held for at least two
years (when I lost track of the guy who had bought the car).  I wouldn't
fly behind an engine with this repair, but seems to work OK on the
street.
