Newer Holley's have the power valve protection designed into them.

1 sugguestion is an entire engine rebuild, its time for it. It dosent
matter what you do or how many time you do it, the 440 is tired and I'm
tired. Thats the only way to fix all this crap! Pull the damned thing
and get it done right once and for all.

Who said it needs an engine rebuild?  I said reseal it and put a chain in it.  That's all it needs.
 
And your right Bob.  That chain is probably stretched pretty good

It has to be..... my Roadrunner (36,000 miles), my old Imperial (76,000 miles) and the new Imperial (98,000 miles) had  stretched chains and  bad plastic cam gears, with pieces probably in the oil sump as well. I would suggest he get an oil pan gasket so he can clear the pick up screen of sludge when he does his timing chain. Backfiring through the carb is exactly what plagued my Roadrunner when I first got it.....and as a teenager with his first big block, revving it up in the driveway didn't help!

Like Big Block said .......check the levels in the bowls.   Holley's don't like low fuel levels.   Pull the sight plugs & you should have fuel trickle just a bit outta the holes.

Like Steve said , change the fuel filter if you have'nt.     Holley's really don't like dirt in the Needle/seats but that'll usually cause a flooding condition which you aren't having.

I'll tell ya a trick I found with Holley's too......On my 6 BBl setup it would get kinda like you're describing,    running rough like it's dropped a cylinder.    I found I could pull the Idle mixture screws out & blow air through the  ( spray carb cleaner might work if you don't have an Air compressor ) Idle holes & all was good.    Just a tiny bit of trash got in there & clogged the idle circuit.    Evidently got past the fuel filter (known good )  & wasn't enough to stick open the Needle/seats but just enough to mess-up the idle circuit.

If carbon starts to buildup around the Air bleeds ( tiny holes on the top of the carb )  that'll cause problems too but usually that takes some time & since the carb is new I doubt they're clogged on yours,   the fix is just to spray carb cleaner into the tiny holes & clean it out.

Holley's just have their own quirks but run great.    You just gotta learn them just like any carb.    Dirt is the worst enemy to a Holley.

Just in case,  I forgot to mention how to adjust the floats.

The screw & nut on top of each bowl is what adjust the float for each one.    The screw is the lock & the nut adjusts the level.   You just barely loosen the screw & turn the nut with a wrench ( yeah,  2 things at one time )   ....clockwise lowers the float & counterclockwise raises the float.   Yes it'll spew fuel while you're doing it.  Hold a rag around it.

I usually do it running & watch but you can shut the engine off & make a small adjustment & then re-start it.  It'll make less of a mess that way.   After you've done it it's simple.

Or make Steve do it!    LOL!
