I don't know if it's different with these sealed beams, but I've used Sylvania Silverstars on numerous occasions in multiple cars, though never a car with sealed beams. I was lucky if I got 6 months out of them with fairly low usage hours, and no I didn't touch the bulb during installation. The Xtravisions last much longer in my experience.
Agree with padgett's comment above about the fans used to cool LED headlights. I don't have any personal experience with them, but I just don't like the added complexity. I might take a gamble on them if they were made by a highly reputable company and not some no-name company as most are. But LED headlights wouldn't be my choice for a few reasons.
My vote would be for a quality set of halogens and add a relay to the forward light harness to pull power directly from the alt/battery and get full voltage to the lights.
