73 Overheating..(and more)

[aeyn <mr85000@xxxxxxxxx>]

Don't look for the catalytic converter, as the 75 was the first
year.  It is probably the heatriser valve, as some one also
mentioned, the exhaust is obstructed by something in the muffler
or resonator.  BTW, have you checked the timing? or the spark
plugs being rated too hot or fouled?
