what heater and rad hoses do i need?

well i checked the rad that i have and it the hose configuration is the passenger side has a hose on the bottom of the rad and the driver side has a hose on the top...anyway that can help me out some? also, just to give an idea, this rad is quite large- im not sure how the smallblock rads looked back in the time of our abodies, but its quite a bit bigger than my slant 6 one....it did come out of a smallblock fifth ave, but im not sure how similar it is to the old style ones
