'91 cams vs. '92 and up

[Nerfdude]

i've read before that the cams out of the '91 KA24DE are more agressive than any other KA cams. is that true? what kind of advantage would a '91 cam-equipped engine have vs. any other? any downsides?

i'm going out to the junkyard probably this weekend in search of a Garrett t3 off of a Tbrid turbocoupe, which i plan to later either graft onto my 240 or sell, and i figure i might as well pull some '91 cams if i can find em, assuming they're worth the effort.

from what ive seen, 91 cams (especially the exhaust) are a somewhat more agressive grind. Im assuming that the duration and lift are somwhat greater, but i havent looked it up ever.
