My situation was very similar but one I got it installed in the boat with closed cooling and a 160 thermostat all is well..... When running on the stand and only getting water temp up to 120 was the intake cool or cold to the touch? Was it sweating bad? Risers too? Mine was and I ended up with a milkshake! Have you run the engine up to temp yet and what was the result?

Does my water mix far enough back for me to run a 3/4 race cam? https://www.youtube.com/watch?v=Rm9qOq_U5FU

I don't remember seeing it sweat - it is polished instead of painted, don't know if that makes a difference. I did see a lot of condensation in the breather tubes. Only got to 120* or so on the stand. It saw at least 160* on the dyno, so it has had a few heat cycles.

160 deg ke bypass thermostat might be the ticket

isn't this just a damn boat motor ..With a moderate cam ................what the ...I have run far bigger cams ..some with lightening headers,, and never had this many issues ..........Or ,should I say debates......Not to be a smartass ,but i'm beginning to think you're afraid to put the motor in the boat and run it ...Could have written a couple of books ..........
