Are the  exhaust tubes from the 65-67 non smog 140 motors that same as
the 68 or 69  140 Smog motors?

I heard someone say that they were a different  material to handle the
higher temps that were experienced with the smog  setup.

Didn't sound right to me but, I wanted to hear other  opinions....

Rick,
Take a look at Bob Kirkman's cyl head article in the CORSA Tech  Guide.  
There you will see that the smog heads had stainless steel exh  tubes. These were 
probably necessary to eliminate the corrosive effects of the  hydorcarbon 
burning in the tubes and exh mainfolds.
