2009 3.5 Pistons vs Valves

I'm sorry I've looked all over the site for a 3.5 specific forum and only see a PERFORMANCE forum... well I just want my 3.5 I purchased to "PERFORM" hahaha
I bought this car and figured no problem - just take the heads to the machine shop and have the heads serviced - or replace the engine with a wrecked one. Wellllllllllll The machine shops are silly expensive (could just order reman heads for those prices) and they also want literally 3 months to do the job which is ridiculous - so I was thinking of just slapping in a set of valves and lapping them in with compound and trying it from there. I made a video of one of the heads and how 10 of the 12 valves are bent - but the exhaust valves are so bad they're hung up on the edge of the combustion chamber.
Anyone with experience with these engines know how tough the valve guides and seats are - if I'm silly for thinking I can just throw some new valves in and run with it? I'd really like to get this thing back together sooner than later, and really dont want to spend over $1000 for everything I have to do. I've found a few engines - I should of just jumped on the engine I mentioned in this video Valves Bent to Heck <---- YouTube video of my cylinder head head. Literally I saw the post mark Pending as soon as I made the video so I missed out on a great engine for being indecisive.

Sad part is the timing belt didnt break. There was some metal ring in the timing cover that probably threw the belt to jump time.

So thoughts? Lap and hope? I cant find a machine shop within 50 miles to take the job reasonably.
If the car companies would spend literally probably $10 extra per engine at most (on millions of engines) they could fly cut the pistons on interference engines and save people thousands and make a reputation for themselves... but what do I know?

$10 is an absolutely huge amount of money per car to an auto manufacturer. Any employee who made a suggestion like that would probably be walked out with all his possessions in a Banker's Box by lunchtime.

If I were in your situation, I would look for a 4.0 out of a Pacifica or a Nitro. You'd need to swap over quite a few exterior parts from your 3.5, but the 4.0 is a newer and all-around better engine, and because it's not plug-and-play for the Charger or 300, they can usually found for much less money.

For more information on this swap, Google "Trashed 3.5, putting in a 4.0", with the quotes.
