Valve Replacement - Info needed

[LarryCV7]

Hello,

I've got a 2010 Audi A4 Quattro, 2.0T/I4 (B8) CAEB with bent intake valves, (all stock, no mods).
Just looking to get this car running again with as few hiccups as possible. The intake valves became bent because it jumped a few links on the timing circuit. I've bought new tensioners, guides, chains. This'll be my first-time replacing intake valves. That said I have a few questions and was hoping someone could point me in the right direction.

When shopping for new parts I've noticed a huge price difference between various brand types offered.
Is there one brand better than others? I checked the OEM dealer prices and thought $60+ per valve was a bit off. Which is why I’m asking before I buy a set.

Also seems there’s variations in what the valve is made of material wise, (sodium, stainless steel, and other performance types). Which should I get? Is it costmary to replace valve springs when replacing with a new set of valves?

Can I get by with just replacing the valves and reinstalling the cylinder head, or should I take it to the machine shop to have it checked for warping as well as having it pressure checked?

Could really use someone expertise that's done this before.

Thanks ahead of time!

Looks about right for typical Audi OE branded vs the OEMs that supply the same pieces. parts page shows the OSVAT 1995SH and the TRW 331125 and Febi 36497 as analogues for the Audi 06D109601M. While I don't like that ECS tends to not document the actual part number by the manufacturer, I don't remember them having "got it wrong" in that regard. Except for the picture for the Hitachi MAF, which they still haven't fixed.

Beyond the OE spec component, I have no input regarding aftermarket performance valves, etc.
