I have installed the Shankle header on my 74 Spider.
It does significantly reduce the clearance. So much
so, that it is now slightly bent. 
In addition, there was a recent post on the digest
that stated that there was virtually no performance
gain for such a unit as tested on a 74 115 Series car.
If any, most of the benefit is usually realized at the
higher rpms, and torque is sacrificed at the bottom
end.
I am retrofitting mine with the original exhaust
manifold and center resonator. It means a better and a
more driveable car for the street.
Wanna buy my header? Cheap.
What a lot of people do is to fit a 74 exhaust to
later cars, but that is only possibly when they do not
have to worry about smog, or have a lot of manifold
gaskets sitting on your shelf and time to swap out the
plumbing.

Anybody heard of any new events in Southern France or
Italy for July 24 to August 6? I could not find
anything interesting in the euro magazines...
