Okay, '72 & '73 heads are the same, so you're set up just fine.  
Having an extra with the temp sensor port is a blessing. It will work 
on the right just fine, but you should hold on to it, because nothing 
else will work correctly on your left. If you end up with a good 
extra pair of those heads, the ones with the vent ports, I'd buy them 
from you someday. They are hard to find.

It's worth checking again, because it can change quickly, once the VR 
starts to wear out.
