[Healeys] Head Gasket

[Michael Salter]

For what it's worth, I always have the block skimmed on 100 engine
rebuilds.
To date most if not all seem to have a low area between 2 & 3.
Touch wood, I've yet to encounter head gasket problems or even the very
common "seepage" issues in the area of the engine number tag.
Fingers and toes crossed.
