[Healeys] Exhaust Manifold Fasteners

[Bob Spidell]

Listers,

I've had an ongoing problem with sealing my BJ8's exhaust manifold to the 
downpipes (the nuts keep loosening and/or the gaskets blow out).  I now believe 
the problem is due, at least in part, to my using flatwashers under the brass 
nuts (the holes on the downpipe flanges are too big for the nuts alone).  What 
do others use to get a good, secure connection here?  Brass nuts alone?  Brass 
nuts with lockwashers (my probable next attempt)? Steel nuts with or without 
washers?

Any and all suggestions welcome.

Bob
