Dave:
These would be engines fitted with catalytic converters. I can guarantee that
a 1972 will have recession problems under normal daily use running straight
unleaded fuel. It won't happen overnight, and you don't gain anything by
worrying. My family ran a fleet of 1973 Austin Marina's and once the exhaust
valve clearances started to move, the seats eroded pretty quickly. I think my
brother went through 3 used heads in as many months being too cheap to get one
fixed correctly.
note "daily use" above. These were cars that were driven daily and did not get
the best mechanical attention. YMMV
