Correct location to hook up heater core??

I am working on putting a Oliver 55 series factory cab on an 1850. Next is hooking up the heater core. What is the best/correct location? The 1850 parts book doesn't show anything but the 1855 lists a 3/8 pipe tee and elbow used to hook up the 5/8 heater hose but doesnt show exactly where. Do these hook in up at front of head where the hydra power cooler piping is? Splice into lines at the cooler? If someone could look on a 55 series that would be great! Does it matter which hose from heater core hooks to where (one line has the control ball valve up in cab)? Thanks!
 
Here is a pic of the 1850 with the 55 series cab that I am working on.

Nice looking set up. I have a 50 series MM cab like that I would like to find a heater core for. It came without heat or air conditioning. Do you have any interior pictures of it?
 
Nobody has one with a cab and heat??

I did some looking and there is a pipe coming out of the head right below the water neck and the temp sender and hydrapower cooler is "teed" in here. I am thinking this is the source of hot water?? Still unsure on the return side. Any pics or advice of what works/doesn't work would be great.

Alan- I don't have any interior pics but next time I drop down the overhead console I will take a few photos of the heater core that is up there.
 
I just bought a 1855 with heated cab but the engine is all apart laying on a pallet.
There is a 5/8" hose barb sticking out the t-stat housing and another one right side of the block.
The latter would be the heater supply
