Are these the right heads for my wife's car?

Have a look at the block in front of your RH cylinder head.
Should read 81A or 99A or something like that.
If it is 59A or C69A or similar ( post war ), that number will be stamped on top of the bell housing.
Canadian C81A heads are a good choice on 38-41 motors.
There was a time not so long ago when you could buy them for $50.
If you miss out on those ones on Trade Me then give Ajays in Waihi a call.
