You can re jet your weber carb for the vortec heads. The weber carb is essentially the same as the edlebrock 1409. There are a few threads here where guys lay out the jetting needed to work on a vortec 4.34bbl carb currently.
That also raised another question I had for the edlebrock 4.3 marine manifold for the 4.3, It's not clear if I can use the same carb, or if I need to buy theirs?
I also located a "Core" 4.3 out of a 97 S10 for $30.
If I get lucky, I might have a donor for the vortec heads, and if I get really lucky the block is rebuildable.
If there is nothing wrong with your current short block take the donors heads to a shop and have them rebuilt. Get marine head and intake gaskets, and intake and you are good to go.
