Whats up fellas. I had a quick question about running an f23 block with an h22 head. I plugged the 2 oil return holes from the head but my last issue is the water outlet on the head. What thermostat housing am I supposed to use and what am I supposed to do with the water outlet on the h22 head? Trying to get this done so I can make CMI on March 8th.

 

Let me see if I understand? You can only use the H22 thermostat housing because it mounts to the head.
Which means you will need to cut the F23 water pipe and an H22 waterpipe and morph them together.

The water outlet on the front of head? goes to top of radiator. One on thermo-housing goes to bottom of radiator and is H22 one.

You used F23 head gasket? and H22 lower timing gear and swapped F23 water pump gear for an H22 water pump gear so the H22 timing belt is right tooth count right????
