I have read the 213 are similar to the 346, and 452 with some extra coolant passages. And that and some later 452's also have the same passages.
But ports are the same.
I also read the 71-72 346's have slightly smaller combustion chambers, at 79cc vs the 73 version at 81.5cc, but that must be taken with a grain of salt.

This engine with just under 40K miles is super clean on the inside, so far, who knows what could be hiding under the valley tin, LOL!!!
The guy I bought the Winnebago from used it for aprox 6-10K miles. He used it to go attend what ever races he used to participate in years ago, and his wife and him would tow the car with it and sleep at the events. So the engine was not worked on by him, except tune up, maintenance, and a new exhaust system.
It even has new tires, and new brakes, and the discs up front are very H.D.!!!
Because the thing had been sitting for 5+ years, he took some stainless metal screen like from a window, and covered the air filter housing inlet ports, and tail pipes in the exhaust, so mice couldn't get in.
So I am gonna guess he took care of it, it probably got its oil changed, but the thing had 4.88's so it also may have been working to go down the road, and I would think that may help keep the sludge at bay.
