My07Bobber -

I'm guessing that you're talking about upgrading your '51 400, which I know (from this thread) has a 288 head installed (for higher compression).

Rather than fussing around with finding, fitting, and synchronizing a 2x2 setup, did you know that the factory offered 4-bbl. changeover kits for 51-54 327s with 2-bbl.?

The first Packard vehicle to sport a 4-bbl carb. was the Pan American concept car - actually, a conversion executed by Henney. The WCFB was then introduced in production for the 26th Series (1953) cars; to the best of my knowledge, it was available and included as standard equipment on all models but Clippers.

The 1951-54 Service Index points to an article in SC Vol. 28, No. 3, from 1954 - though the title, alone, may be a bit misleading at first glance.

These kits are also listed on the first page of the Fuel section of the 1948-54 parts book, but with no details - other than three different kits for 1951-52, 1953, and 1954.

I've not seen or studied such a changeover, but doubt if you'll find a complete NOS kit for your application. Given the three different kits, you'd likely have to find a 51-52 donor car.
