I have used MMO as a fuel additive for my small engines and outboards for years and have always gotten long, long life out of them. I also mix it 50:50 with Kroil and use it as an all-purpose cleaner/lube for firearms. For the auto rifles, pistols and shotguns that like to run wet I keep them lubed up with that mix. It seems to lube without gumming up with combustion residue. When my FIL was in the marina business, he used to use MMO to fog engines when winterizing them, as did his father. One tool and die shop I worked in kept MMO around as the penetrating oil of choice, but I never thought it was worth a schitt for that....not even on the same planet as Kroil.

Airport probably has 110 low lead for sale if there’s one close by.

Interesting.
Even though the flat head arrangement is different....I still don't know how the lead would lubricate the guides.
It pulls aif fuel past the guides...not through them.
After they went to positive seals....guides wore more quickly. Some consumption past the guides is necessary.
Unleaded gas will damage seats however.
Hmmm....Interesting.
Wonder how it was supposed to lubricate the guides? I just assumed that it left deposits on the valve stem which served as a lubricant between the stem and the guides. But it's something I read long ago. I don't recall the particulars about it. From what I'm reading now it seems that lead is more beneficial to the valve seat than the guide.

Wonder if VP race fuels has something similar? You can get that by the drum.

Yes.
I believe that lead stopped the "adhesion" of the seat to the valve.
Like little microwelds. Seat depth would increase over time.
Hardened seats cured that.
Far as I knew....a little oil pulled by the stem was always the lubricant.
Not sure anything but lead would stop the adhesion problem.

Get you a lead substitute for the gas, and Rislone makes an oil additive with ZDDP. ZDDP was used by my neighbor on one of his motors for the valve seats.

Thanks for the replies. The old motor was completely rebuilt when the tractor was restored. I'd like to keep it as fresh as possible. I've been lazy about not treating the unleaded fuel I'm running in it.

Frogsnacks.
It was not uncommon to rebuild them with better seats.
Sometimes.

MMO is the go to product for unsticking rings with these guys Yeah, I can see why they would use it. An old guy that worked with me at the automotive machine shop rebuilt those old Kohler flathead V4 motors that used to be used on everything. He would start them up and let them run after he rebuilt them. He always added Marvel Mystery Oil to the first tank of gas in a freshly rebuilt motor. That's the first time I had heard about it.

Sometimes. The old 8N was restored back in the 80s. It set in a heated garage since then and just started up occasionally. It had 8 hours put on it when I bought it. I've put about 40 hours on it.

I just read where Ford was already using a hardened seat by the time your engine was made.
