170/6 build plus questions!

Thanks, I am thinking I may just port/polish the factory manifold. My goal isn’t a race car put a fun curvy road toy...

After your done with the exhaust manifold, maybe Jet Hot ceramic coating inside and out. Not only does the 2 barrel intake and carb give you more power, you get better mpg also. I would get high 20's cruising on the highway when I was done.
