I have Integra with k20a2 I kept the heater. Having some issues though.
The issue is the metal heater pipe and all the small 5/16 hose barbs not being used.
I removed all the barbs from the upper radiator hose neck with pliers then drilled them taped.
Used an Allen head plug with hondabond...
I remember seeing a thread on someone blocking it off but I can't seem to find it. I'm getting ITBs soon for my k24a2 head and I was just wondering how people block the coolant port off? Trying to do it with the motor still in the car so simplicity would be the best!
