What is the correct valve cover breather for a 1970 Dart with California emissions - 340 engine and 727 trans? Is it 2 or 3 nipples? The carburetor will be a standard Carter AVS. I know one of the small nipples is for the fuel line vapor, but not sure where the second small nipple goes to.

2 nipples for '70 /6 with N95.

3 nipples for '70 V8 engines with N95.

One small nipple to the carb vent port & one to the line on the inner fender for the V8s.

A body should only have two, if you have 3 something is wrong. J/k.

I think to the tank via the line on the fender Alaskan mentioned
