Blown head gaskets were very common with the Vegas. I had always heard
its because of the use of the block and head being dissimilar metals
with an insufficient gasket to allow for expansion variations.
The problem you noted I believe was another bad issue with this engine.
The Vegas were just lousy all around!

The head gasket problem was also an artifact of the poor cooling
issue. Putting a 3 or 4 core rad in made the vega a MUCH better
(albeit still lousy) car. GM has NEVER figured out how to make a good
small car. Their captive imports tended to be somewhat better than
their American produced stuff. The Vauxhaul Viva HC (sold as Firenza
in Canada) was not a GREAT car, but in many ways was far superior to
both the Vega and the american built Chevette.
