Diagnose extent of damage from stuck valves?

My buddys ford 460 has stuck valves. Where do I start? Could I notice anything by removing the valve covers, or do I have to remove the heads?

Is it possible to unstick them without removing the heads? Assuming they stuck from sitting.

What's the chance it bent the pushrods if it was running when they stuck? Can I check this without removing the heads? I'm not too familiar with this engine.

Can I put a dvd player in my van where the vcr was?

I bought a 2003 Ford Windstar to accommodate my growing family. It has a vcr in it. It plays tape.
But I was wondering if it were possible to update it and put a dvd player in there instead? My kids are 9,5 and 4 mths. So they movies they would be into are not on vhs. Apart from older disney movies which are a big hit but ya know, they're all sad they can't watch Frozen on it
As the driver it doesn't bother me if I can play dvds in there. I'm not watching it haha
So, is it possible?

If turbochargers are better why do companies put superchargers in their Highpowered vehicles?

I'm told and showed numbers all the time and explained why Turbochargers are superior to superchargers. And the whistle/spooling of a turbo charger sounds alot better than the whinning of a supercharger… Why do companies put superchargers on their big motors?

Cars like the Veyron, lambo and others all come Turbocharged and are some of the fastest vehicles on the planet.

Why do companies like Chev, Ford, Dodge put super chargers in Their ZL1, GT500 & Hellcat. Since turbochargers are apparently better wouldn't they get better numbers / more efficiency?

Added (1). @Mel… But again, some of the fastest (Modded) Drag cars in the world (Without nitrous) run Twin Turbo's, and get insane numbers. Wouldn't a good turbo have barely noticeable lag and more reward after it spools up?
