Friend throw those junk pipes as far as you can . I hope you didn't ruin a good engine with those . You can find good used exhaust manifolds in the swap section cheap . Who ever sold you those should be nutted .

If the milky oil started after installing those abortions then be assured they are the source . Are those water cooled ? i don't see a water inlet . Water coming into cool engine exits via the water cooled exhaust . There is a wealth of information here , study and ask questions before you do anything . Don't be the " Knowledge gained is in direction proportion to parts ruined " guy . Lots of good guys here willing to help for the asking .

Yea , that's what i was getting to . Hope someone didn't plug water dumps on thermo housing to run dry pipes .

That's proof positive right there that's your problem . Check for damaged valves and guides and hopefully it's limited to that .

After doing the heads I only took it out on the water for ashore period of time you think it could of damaged the valves and guides?

Fresh oil and a compression test will tell you about the valves . Who knows , you may be lucky . Water on hot exhaust valves turns to steam , up the valve guides it goes and condensates under the valve covers , water droplets then drip into the oil turning it to milk .
