You have a manual transmission, so it's super easy to manually rotate the crankshaft. I copied this from my shell blasting thread.
4. If you have a manual transmission, this is easy. Put the parking brake on, and jack up the driver's front wheel. Put the transmission in 4th gear and turn the wheel counter-clockwise only! This will turn the engine's rotating assembly in a clockwise direction, as viewed from the crankshaft pulley. If you need to jack up the passenger side instead, you must turn the passenger wheel Clockwise only!

You need AC Delco 41-108 (iridium) plugs. No substitutes. Check them if you must (carefully, they're easily broken) but they're pre-gapped. Modders with really high boost reduce the gap but that risks breaking them.
The "sensors" of which you speak are not sensors, they're the VVT solenoid valves. They sense nothing. (I care only to avoid confusion.) The two camshaft position sensors are on the front and back of the head, drivers side.
P0017 remains an urgent concern. It almost always means a mis-timed exhaust cam. Maybe alway, not almost, IDK. With deferred oil changes, valve part of a solenoid solenoid valve can gunk up as can the cam phaser, but your case looks pretty clean.
I don't know how to determine with absolute certainty that it's timed correctly without taking the cover off, BUT you can check the relationship between the two cam sprockets by countingteeth chain links.
In the video the chain slack does not look like it's enought that it would allow the chain to jump. Make me suspect that they bungled the chain job. You might as well forge ahead and remove the front cover.

Yes there is slack in that timing chain. I would change it for sure. For the 2.0 Turbo you do not change the balance or timing crank sprockets, those are SS specific. So Ofer the chain kits with out sprockets
Cloyes 9-4201SX and 9-4202SX. That way you aren’t tempted to change sprockets and mess your engine up

took me a while to get the colored links on the sprocket marks. Used a sharpee to help and the exhaust sprocket is 1 tooth off. You guys were right.

Ordered a pair of Dorman cam bolts. Plan is to check TDC with screw driver, ziptie the intake cam and chain together, pull chain tensioner, remove top guide, remove exhaust cam sprocket bolt, realign one link over on exhaust cam and torque new bolt 22ft lbs then 100 degrees.
probably will have to remove engine cover to make sure the crankshaft pulley chain is correct.
also i alway hand tighten my lug nuts then torque to 100-120ft lbs. previous owner must have used a breaker bar because i had to use a breaker bar to get 4 lug nuts off on the passenger wheel and stripped the 5th. Freakin nuts lol.
