Pretty much the same on all small block Mopar engines, and though this pic shows the ones to seal because they go into the water jacket, some of the others on the timing cover go into the block where oil is.
It's not pressurized oil, but can still seep around bolts if they are not put in with sealer.
If you end up having the timing cover off it's easy to see which ones, but otherwise it's not a bad idea to RTV the threads on all of the bolts just in case.
Sealer on the bolt threads that do not go into the block somewhere won't matter.

-- Wrong water pump - hose connection is on the other side.

The water pump itself isn't the point, the bolts that go into water jacket are.
All four of the long ones, two above the coolant ports in the timing cover and block and two below.
Here's a different pic if it makes you more comfortable.
This is right of the Ramcharger central site and a 318.

-- When I first pulled a bolt, without draining any coolant, I pulled the one on the top of the passenger side first, and no coolant came out , with the bolt completely out. ( the coolant was completely full, up to the radiator cap). -- This makes Me believe that that bolt does not go into the water jacket. -- See post # 3, and 5. By testing that is apparently the situation - 3 bolts in water. -- I did not pull the 3rd , wet bolt, because it is under the fan pulley.

Ah, apparently I am so used to sealing all four of the long bolts in my mind it was a water jacket bolt also.
I always seal all four of those and all of the timing cover to block bolts because of oil.

--- For now, I'm just sealing 2 of the 3, that go into the water. -- This all started when I adjusted the power steering belt. The 2nd bolt down on the driver side. -- Thanks for Your input.-- Ah, apparently I am so used to sealing all four of the long bolts in my mind it was a water jacket bolt also.

I replaced the water pump on the 318 in a 78 Dodge van I got cheap and I know some of the bolts need to be sealed but I don't remember sealing any of them.
I don't drive it, I use it mainly for water tight rolling storage but I might need to move it around or actually haul something with it.
I left it sit dry for almost a year then decided to put antifreeze in it and the area around the upper passenger side bolt started leaking once it was full.
I guess I forgot to seal that bolt and I couldn't remember which ones were critical so thanks for this old post, plus mentioning RTV is fine as I don't know if I still have official thread sealant but I have plenty of silicon available.
