Thanks for the input, however, the NADA or North American Dollar Area Land rover 2.6 ltr engines were introduced with the westlake head which were fitted to increase horsepower for the American Buyers. Thus the head gasket set for this engine is quite different for the US vs. the UK. I owned a 2.6 thus the reason for me having the set. If I am mistaken in my facts or if you have any other information regarding this engine that could be of use to other NG readers, I would hope you would share it in a kind and considerate manner. As well, regardless of how available something in the UK maybe, that does not mean that it is common here in Canada or the States.
NG's are set up so that people can learn and share in knowledge, expertise and parts, not be abusive, ignorant and hurtful. Please keep that in mind next time you "share".
