Lost compression - after head change
#23
A low compression gasket will work in conjunction with a high compression head, in so far as it will seal and run. The problem comes because of the wider sections that stick out into the combustion area - they burn off.

L/C gaskets are much thicker than a H/C gasket and are a little more forgiving on a warped head - I carry one in all the cars as "get you home" spare - I have had to use the combination (h/c head + l/c gasket) once, hence why I know that it will work, at least for the 300 miles needed to get me home on that occasion!

Do let us know what the problem turns out to be - something simple I hope.
