PI swap and toss on the 99+ Tork Tech kit. I don't know if you'd be able to use the blower in the same manner as you could with a PI intake on NPI heads, but I wouldn't see why not? The PI heads would take advantage of the boost though.
How different are the ports from the 96-98 heads when compared to the cobra heads? I don't know but am curious as well b/c you see the 112 eatons all the time for next to nothing.
