2300 Rebuild Kit - Which one(s) exactly?

[jaskispyder]

Hi, I am new to this forum, but have been researching all I can.

I have a '73 1210 with the 345.

I am at the final stage of deciding to rebuild my carb or send it out.

Can anyone provide the information of what kit I need to properly rebuild this:

2300: r6394-1

I heard that Holley 37-474 is a good kit, but doesn't contain the correct power valve.
Then read that Holley 3-888 is the correct kit

then there is the napa 25529 with the correct power valve, but a different float valve adjuster.

So.... Anyway which kit should I order?

Thanks!
