oh by the way.. to do the lower manifold bolt on number 8 be prepared with a socket UJ plenty of swearing and fiddling about its right ***ker.
i found the way to get the manifold gaskets on was to line up the gaskets on the thread of the bold and wind top on number 8 in gently *by Hand* you don't want to bugger the thread up and then number 3 and get the rest in by hand. the metal gaskets are sized to grip the bolt on one side. but torqueing that final lower bolt on number 8 will lead to cursing. Rave says to remove the Steering rod.
however MartyUK suggested the way he did his was to remove the wheel and the wheel arch liner and you can get straight on the bolt that way with an extension. i couldn't get the steering rod out so spent ages buggering around by feel to get it torqued up
