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.
