I think it is possible to fix them, but I opted for not, as the details of the 
fix were not very agreeable to me.

All the heads are interchangable.  Only details you have to worry about are: 
With the '77 there was a water hole for the water choke on the carb that is not 
used in any other year. And G engines don't use the same valve train & lifter 
system.  You need to preserve the one on your engine. (18Gx only work with the 
18Gx series and the 18V only with the 18V series.)
