[Healeys] OFF WITH HER HEAD!!!

[Dave Russell]

Hi Bob,
Not sure how good a compromise copper gaskets are. The whole idea behind 
MLS gaskets is that the head & block are free to move in relation to 
each other, as they expand & contract under temperature differences, 
without breaking or harming the seal. AND, they do move. 

The stock copper-asbestos-steel sandwich gaskets allow this relative 
movement but the asbestos center is weak & prone to permanent distortion.

Solid copper does not allow the easy "self adjustment" that MLS & 
sandwich gaskets do. It also loses strength at elevated temperatures.

I guess it's your choice.

Regards,
Dave Russell
