When I say it dies at WOT what I should be saying is if I gun it from idle to WOT it can die ( choke it seems) . If I tickle it through the intial stumble then slowly increase to WOT. It goes great. If we are planning and I go straight to WOT it does not miss a beat it just pulls .
the part changer at the dealer (can not call them a mechanic) did not clean out the accelerator pump passage. on a holley, that is on the bottom of the fuel bowl and first to plug.
you are describing a failed accelerator pump circuit. again, your carb is fine, just needs $10 worth of cleaner and gasket. this is something you could even do.
you are not getting fuel thru the squirter.
stop going to that mechanic.
get a bowl gasket and a metering block gasket. if you do not know what you need. go here

and download the spreadsheet I put together. look for the list number you have and get the appropriate bowl and metering block gasket.
if the ones you have are blue, they are reusable
disconnect the fuel line
pull the 4 bolts on the face of the bowl, these are #12 screws and you will have either a hex or a slotted screw head
use the handle of the screw driver and tap the bowl on the side to crack teh gasket loose. to not pry
same goes for the metering plate
now at the bottom of the bowl where it meets the metering plate is a small passage. that is plugged and needs to be mechanically and chemically cleared
the ONLY way to clean that is with solvent and manual probing. they need to run a fine piece of copper wire or fishing line thru it to ensure it is clear.
and no, you can not simply spray carb cleaner from a can and hope it works.
