How much damage would it be to the electric planer blades getting the paint off 4/4's? I would like to shave it down to 3/4's trying to use the original wood. Or would it be better to shave off the clean side and install it with the clean side out?
TIA
What kind of paint? Lead may be present.
Personally, if I was relatively sure no lead paint was present, I would probably strip the paint with a belt sander, then plane it.

I believe it may have lead. I took off the moldings and smelled lead.
A lot of paint contains solids that will literally eat the knives of a planer... I'd plane the unpainted side and hide the painted side.

Thanx, that I can do since the painted side wont be seen at all.
If it's not critical to get the paint off (ie you're not gluing it and the back side isn't visible) then leaving the paint on is likely your best bet.
Alternately, you could just shave off a sixteenth with a big flat bit in your router. The carbide will hold up to the paint better than steel planer knives.
I've also done it with scrapers and an angle grinder, although with abrasives I'm worried that some of it will get stuck in the wood and nick the planer blades.

I'd take it outside and hit it with Zip-Strip. Fast and easy. With painted wood, hidden nails are as much a hazard to your tooling as abrasive paint. If you're using carbide cutters, nails are also liable to create shrapnel, particularly hardened masonry nails.
What does lead paint smell like?

I'm not doubting you because I don't know but what could be in paint that would damage steel knives? Not the oil...not the resin...titanium dioxide?
clean side out?
Start with paint stripper and a scraper. It also keeps the paint in one peice and dust-free so it can be safely disposed of, and it sounds like the wood is flat sided. Once you can see wood you can tell if there are nails. Get those out or punch them in deep before using your planer.
Does anyone know, was lead just used in glosses and topcoats, or do you find it in undercoats and primers too?
A set of planer blades costs me about $45,00. So I remove the paint before using the planer. I do not like to remove paint. It may contain lead and other stuff.
When it is necessary, I use a hot electric iron or a hot air gun. If the coating is very thick, I use a flexible blade scraper.
When the coating of paint is not as thick and more so with latex paint I use a normal scraper and I maintain a sharp edge and angle with a bastard when the scrapper becomes dull. I is useful to have various sizes and shape of crappers.
I have use carbide blade with some degree of satisfaction. The problem is to re-sharpen the edge.
Silica (basically sand) calcium carbonate, talc, and kaolin gives paint it's body and durability these days. The silica in particular acts as an abrasive and wears jointer and planer knives quickly and the other fillers aren't much kinder.
The last time I tried to run painted wood through my jointer will be the last time. I thought I could get away with jointing the edges of a pre-primed board that had been ripped on the table saw. Wrong... I ended up with two grooves worn in the knives that left humps in the surface of the boards run over it later.
A lot. I learned about this last June. Too much of a hurry, put a wide painted board through my planer. The board had been on my house since it was built 60+ years ago. I got 4 passes on freshly sharpened knives before they just wouldn't work anymore.
Live and learn.
The knives have been resharpened.
If you're concerned about lead, removing it with heat isn't the wisest way to go about it. Chemical strippers and chem-resistant gloves would be a better idea.
Each case has to be analysed. Each project is handled differently. A 50 years old plus exterior front door used on a house compare to an old French finish on a walnut dinning set are very different. As much as I can I try to avoid using chemical. I do not use heat all the time and when I do I wear a proper mask. Most of the jobs are done with hand scrapers of various shapes and configurations. I have used chemicals and learned that using scrapers takes me about the same time or better.

do anything to steel. Silica is a different story. Thanks for the answer and links.
I cant explain the smell but I do notice it when the paint chips come off. I rather not taste it.
