Default What is correct vacuum hose code and kit '77??

I am going to be ordering a new vacuum hose kit for my '77 L48. It is a Hi-Altitude set up, pics of head and carb below. But, I want to get the correct kit. Am I right that my set up would be an "Na6" code and require the "Nb2/Na6 Emission Kit"?? Or would it be the "L48 Exc. California" kit?? Couldn't find a good answer on the web.

Any help is appreciated. Thanks!

Yes to the NB2/NA6 emission kit and nice job providing all the facts, and photos up front.

Not a surprise...web has almost become another source for fake news! But the "L48 exc CA kit" means all L48s but California equipped emissions.

I agree with the above. All L82, L48 high altitude and L48 California cars would used the same hose kit.
