KH cylinder head

Postby kevinbowman » Wed Jun 10, 2020 9:52 am

After having problems trying to seal the head gasket on my KH I striped the head and barrel to find out, one that the gasket I had been using was a patten one not having the sealing rings around the push rod holes (thanks to Paul Wirdham for the information) two that the head and barrel we not completely flat. I have now got the correct gasket thanks to club spares and the head and barrel have been surface ground the barrel needing 3 thou and the head needing 10 thou to get perfectly flat. Engine has been reassembled and ready to roll so the big question is at what miles to retighten the head and how many times before the gasket is fully compressed ?. Any replies gratefully received as I don't want to end up in the same position with a leaking head gasket. Kevin Bowman.

What material is your head gasket? I am still using NOS copper asbestos ones so I don't know what the Club ones are made from.
