It shouldn't matter which port style you use SVT cams with when not using the 2.5L UIM (like you shouldn't unless properly modified, which raises more issues anyway).
The twin port Taurus UIM no longer has the bifurcation between runners so it is a shared port but still allows the use of the IMRC for lowspeed cylinder filling. So there really is no benefit as far as dual runner acoustical tuning either way unless you use the 2.5L UIM (which is inadequete).
Hybrids have a fouled up combustion chamber and could use some work but the return may not be practical for the amount invested. The higher CR can work against you at high engine speeds and puts more stress on parts.
I'd just as well use a late model engine unless you want to spend the money for an electric water pump and still use the twin ports with IMRC.
