If your breather box has only one plastic plug and has a metal tube 
extending down from it to the oil filler pipe, then it is the '68-71 
version. That version doesn't use the heads with the vents. In that 
case, plugging the extra air filter ports is definitely the right 
thing to do. (If you don't plug them, those open holes will allow 
unfiltered air to get sucked into the engine.)

Sounds like you may have an earlier engine. What's the engine number?

That part # is probably on the breather stand. I think it's the same 
for all years.
