Funny you should mention, there has been a persistent coolant issue that I cannot solve. I put in a new radiator a few years back, my mechanic found a couple of freeze plugs that were in bad shape and leaking, and yet there is still a slow leak. It never goes terminal, but I have to top the damn thing off. I have wondered a few times if I’m a nut job for keeping this running.
The only intake manifold gasket I’ve changed in my storied career was on one of my BMW E30 325i units. That was a tricky job, but it did the trick. It was going into loping at low rpm, I would be herky-jerking around turns.

Very easy job. Unbolt the IM and bolt it back on with the new IM valley pan gasket after cleaning up the corrosion, and use plenty of appropriate sealants. It was so common that it is amazing your example lasted so long without having that done. I knew a guy that recommended it as preventative maintenance to his customers. and they all loved him. I was first alerted to this when I witnessed him doing one and asked about it. I took my 307 apart and was astonished at the corrosion about to be a problem and thwarted it in the bud. namaste
