Have an O2 fitting welded into one of the primary tubes (typically back passenger side). Run a pipe from there up to the intake manifold EGR passage. The one I saw was a ZZ3 engine (aluminum Vette heads) and a Vette-application Big Mouth TPI base.

it can be done
i did it
just cut off the pipe from the vette manifold(headers) welded it into my headers and made a pipe up to connect to the manifold
wrapped it with heat wrap no hassles at all
