Need help finding parts+identifying engine

[Aint Ashamed]

I recently purchased a project boat with 2 international diesel engines. I was told the ¿valve manifolds? Are cracked and caused the starboard side to have a stuck valve. I’m having issues locating the marine parts for these engines and would be grateful for ANY help.
Trying to figure out how to attach photos for reference
