Jim, that might not make much difference for most people, but I would be willing to bet that someone who has to undergo a dyno test for emissions might have a problem passing. I also wouldn't want to try that on the Camper Special 390 4V I had, it used a moderate vacuum first stage and something like 3.5" second stage. The carburetor had a passage in the throttle shaft that bled air to the power valve chamber at WOT. I don't think you could get anywhere near the right balance on that setup.

Rebuilt carbs
I posted this in the topic specific forum, but no replies, so...
I want to get a carb for my '85 460 to rebuild at my leisure (and in case I screw it up). Is there a site somewhere that has a list of what mine might have been used on other than my F-250?
The numbers on mine are:
E6HE-9510-AC
LIST-50305-2
1336
Just in case anyone happens to know off-hand.

Don't shoot the mesenger.
I'm just pointing out that there are NO more 2-stage valves being produced.
Go ahead and read for yourself...

An addendum to the 3-1346 kit instructions indicates that Holley is no longer producing 2-stage powervalves.
They have a chart offering best choice single stage valves depending on the number shown on the 2-stage you now have.

As for 37-1536 containing floats, I don't know. When I contacted Holley I asked for the needed kit number and any part numbers for any other parts I might need. The person didn't mention floats or anything. I don't know if that's because they are included in 37-1536, or if he just ignored that part.
I think I'll reply and ask the difference between the 37-1536 and 3-1346 kits.

I was going to mention that, then again, the caveat under the photo makes me not put a lot of faith in it. I emailed the guy back and asked the difference between the two kits, and if the $100 contains the floats. Though if that's the only difference, it's still not worth it.

I think he wants you to buy the nitrophyl ones instead of brass....
Google image search shows a number with the same disclaimer but none with floats.

With most carbs, a bad float is a rare occurance. Most kits I have used do not include them.
The power valve on the Holley's and some of the Ford carbs, is what it is. It's not the most precise way to add fuel but it worked in the old days. The 2 stage was just another stop gap attempt at emissions. That's one thing the edelbrock/carter and the quadrajet's had over the holley's. Their needle/main jet combinations are much more precise than the powervalves

Well, after asking a number of times via email Holley finally said the 37-1536 kit replaces the 3-1346. So I ordered the 3-1346 (based on the statements here) from Amazon.
Now to find a rebuildable E6HE-9510-AC LIST-50305-2 carb. I'm starting a new job next week and can't risk having the truck out of service in the event I run in to any issues rebuilding it.

hey all, been reading the thread..had the same issue with mine, but got the holley rebuild kit off amzon..
well as far as my truck..looks like someone swapped a 70s 460 in my truck, from a car most likely as the setup looked original..after the freeze plugs went..I knew it was old and unmaintained..no 20mpg, but the truck was from CA.. the guy had no idea how to maintain, which is why he got rid of it..fyi..3g alt swap is way to go! (because it will come up eventually if not already, I know!)
Good luck on the rebuild!
