Replacing cylinderhead

[Ian Williams]

I have used solid copper gaskets but don't think they are the answer for the average seven, they handle high compressions and on a dry decked racing block would be good but they are very difficult to seal if you have water ways passing through. I never had a problem with old stock gaskets when I first started playing around with sevens as a 19 year old, now almost 40 years later I see a lot of engines where the gasket has been seeping. The old copper asbestos gaskets compressed much more than the current product and as I said earlier this is I believe the issue.
