The question is: We are installing a 4 into 1 header, does the chassis need
to be relieved to accommodate it ( it seems that it does ) or is there a
special trick? It is the original S3 chassis. There was a comment in
Classic & Sportscar that indicated that one is not supposed to relieve it,
but it was vague.

installation of any headers in Elans is tricky though. Sometimes, you'd swear
there is just not room to do it. Mine came apart and there was a magic
sequence necessary to solve the puzzle.

one or the other needs to be 'relieved'. Not all 4 into 1 headers come
from the same manufacturer or batch, some fit better than others.
Make sure that there is not a separate problem such as bad or incorrectly
installed engine mounts, missing or short spacers between the block and
left side mount, bent frame, etc.
If it is determined that the frame is in the way, the flange should be
curled back nicely (not cut away) so as not to cause stress risers and/or
Making room for installation is a separate issue - don't cut or bend the
frame just to get the header onto the studs. Rather, loosen or undo engine
mounts, jack up & down, use prybars for side motion etc. Also make sure
exhaust studs are no longer than necessary.

of it and the engine support is so little that the rubber has been burnt and
the engine was not supported so I had to make a steel sheet protection about
to make isolation between support and manifold . Since I done it all is
