TGW won't know anything about the sixes, I suspect. They probably sent you the grommets for a V8.
The six valve cover has two grommet ports - one for the PCV valve connecting to the manifold, and one that admits filtered air to the crankcase from a filter in the air cleaner.
Prior to '76 the filtered air connection was a molded hose with one end that fits into the valve cover top. From '76 on, this uses plain hose with a hard plastic elbow that goes into the valve cover grommet.
I believe this elbow is the same size as the PCV valve, and you need two each of the same grommet to fill the holes. Looking at my '77 and the parts book, this is correct.
