A few of you have asked me about the Clifford header I was using on my 72 240. I did some research and found their website. They specialize in 6cly performance and will still make headers for the Z-car....There was a write up in Grassroots motorsport some years back about these headers on Z-cars...anyway...if you have any questions about the quality of these units, fire away. Their site is http://www.cliffordperformance.com
and you can see them on my old car at www.geocities.com/superb60ce

Ciao,
Russell
