I have tried most headlight options so I can give what I believe unbiased opinion.
If your wiring is in good shape and you want to stay original get GE sealed beam hey are surprisingly bright for OEM sealed beam and will give plenty of light for most situations
When I restored the car I wanted better lighting for the country roads I use often and as other have said Vintagecarleds are an excellent choice I have their VC3500 with Classic lens option in 2 of my cars
I prefer the classic Lens as it looks like a Cibie lens
On my White Roadster I Have H4 style lenses retrofited with LED bulbs instaled by the previous owner , I'm not crazy about the lenss but they perform as good as my Vintagecarleds but cost about half the price, so when it was time to do my 510 I did the same but with a nicer lens
Finally here's a good comparaison between LED and OEM (yup my stock one needed re aiming lol)
Low beam
High Beam
Position lights
