Yes good choice of gaskets. Mace kit is quality. The LIM gaskets are the most common place to leak.

Does your Eco have a water pump bypass hose on the front? I had an idea early Ecos had the front adapter. They can leak there as the original ones are plastic. New ones from Repco are cheap and made of brass that last forever.

I have a VY, and sounds similar
I have a milkshake in my radiator and I have purchased a full set of LIM gaskets,
Being I have a Super6, I have a bit more hardware to remove and re-fit with gaskets,
I also have a serious flat spot when its cold, and after it warms up, it runs great.
So I am guessing the LIM is losing vacuum when cold [everything has contracted],
Just a need a clear day with no interruptions to get stuck into it.
Just hope it not head gaskets,
I probably should do the Head Gaskets since I have it pulled down that far, with the other hardware removed,
But will see how it will go with the LIM gaskets.

I'd be pretty confident that your head gaskets are ok. Pretty rare they leak on Ecos and Buicks.

I'll admit i had to figure it out a while back. Buicks like i have, don't have a plenumn like the Eco does so i normally called it a valley cover or intake manifold and not lower intake manifold, because there really isn't anything above it.
