I looked at doing this with my Alfa but after doing some research, I decided to go with halogens and relays. The buckets and lenses for our incandescent or halogen lights weren't designed for the way LED's are made. It's like trying to wear somebody else's eyeglasses. The only way to get proper throw of light down the road is to replace the entire light with a unit that was designed to work together. There's a thread on Jalopnik that was basically written by Daniel Stern, an expert on car lighting, that goes into great detail about all this: https://jalopnik.com/why-most-led-headlight-upgrades-dont-really-work-an-ex-1843070472
One upgrade that does work is installing relays to supply the power to the headlights. On lots of older cars, all the power for the lights goes through the headlight switch. By changing that so that the headlight power goes through relays, the output will be better and you might save yourself from having to buy a new headlight switch ($400 from Centerline).
Yeah aftermarket PnP LEDs in halogen housings almost never work as well as they should, usually kinda pokey beam pattern, often increased glare and alot of foreground, which is amplified by the bluer light. Which makes it harder to see down the road.
Some of the higher-end PnP LEDs work pretty well, such as the Morimoto 2stroke 3.0, Diode Dynamics (which are American made) and GTR lighting.
Usually a reputable full LED replacement housing ( like JW speaker) is your best bet for a substantial light output upgrade in terms of pattern and lumally just do not look right in a classic car.
I built a set of HID projector retrofits for my old Malibu Im not a fan of the look as I rather have fluted lenses but not much you can do with 4x6 aftermarket or not, let alone have classic looks.
Even if the performance were good, I think most inspection stations here in Virginia will fail these since the bulb won't match the lens.
On the other hand, the LED tail and signal lamps are a great thing - brighter than incandescent and noticably quicker to light which might help keep the guy behind you from ending up in your trunk.
Turn signal relays may need changing.
There's a company that does stock-looking 7" LED retrofits for those who don't want weird bug eyes on their classic but want modern lighting.

They don't have a set of 5.75" lights in that style yet, but when they do my Cadillac is ready.

Virginia has some non-typical regulations about headlights. They were a particular challenge to deal with when I worked for Saleen. All of the headlight changes had to be adjusted to pass the VA rules. Several cars were effectively impounded before sale/delivery due to headlight issues...

I dropped a set of BEAMTECH LEDs into my H-4 Hella 7" lenses in my 1980 RX7 and the results were transformative! Clean, bright, white (not blue!) illumination that makes night driving a pleasure. Again.
Its like my eyes just instantly became 40yrs younger! All this and NOT baking my 40yr old tiny headlight swithc wires. Oh, and under $40 on Amazon. INsane. Best lighting upgrade you can do...

How well do LEDs take... oh something like headlight rollover? Like on an Opel GT. Been considering lighting updates on mine. Concerned about the jarring of opening and closing the headlight buckets. They do take a little force to click into the lock position, both opening and closing.
In reply to paddygarcia :
I put LED's in my 67 Sunbeam that's tagged historic here in VA. No inspections and no issues with local LEOs.
I really, really dislike LED headlights on old cars, but I love, love, love LED tail lights.
I bought 7"LED headlights from Amazon for my modified 1961 Jaguar E-Type and installed them with a relay and they work beautifully....I had to snip a minimal bit of clearance out of the buckets and plugged them in....best highway lighting this car has had since it was built on my 23rd birthday back in October 1961.....HB
