Help me pick front calipers

i have been doing alot of research on this and i think that i am going to just try the 4 piston wilwoods with the 4" total piston area and see what happens. this is the cheapest way to go as the calipers only cost $140 ea. this will get my car rolling for the time being and i can always up grade later. they have to at least work better than my factory 9" drums did.

Oh they'll kick the crap out of the old drums!

That's not really the issue though, the real question is how they'll balance with the 12.19" rear disks. You'll definitely need a good adjustable proportioning valve to make the whole system work as a whole, otherwise you'll end up locking the rears under hard braking.
