Heater Hose Ports

[zertek]

Hey guys.

Just a little something im not to sure on about my heater hoses. Engine is an rb25det and is getting dropped into my 32. As you'd know, there are 2 heater hose ports on the inlet side of the block, each next to the nock sensors.

My question:

Is one of these a sender, and one a return?

I have joined my turbo water line up to the small nipple off the heater hose port at the back of the block, and blocked off the small nipple off the heater hose port at the front of the block, as per my greddy plenum it has no where to go.

and does it matter which port i tap into either heater hose on the firewall? ie front heater hose port to top heater hose on the firewall.

Or is there a 2 way valve in the heater somewhere and it doesnt matter which direction of water flow?

Really hope this makes sense... i suck at explaining myself

cheers!!

oh forgot to mention i am also running an oil cooler and filter relocator so i dont need the heater hoses to join into the stock oil cooler system that ive seen on most rb's. So it would just be heater hose port direct to heater hose on the firewall. I just need to know what order

Thanks
