Cam Phasers - Won't go back on.. (Bank 1)

Howdy - me again...

I did lifter/rocker job on Bank 2 - wasn't easy but got 'er done. Still had tick, came bank to do Bank 1... Job went smooth until time came to put the phasers back on to the cams.
I fought with the phasers for an hour and almost had them both on but not flush, I went to slightly back one of them out to try to get more leverage - the entire thing rotated. Both phasers were pushed out, the plastic wedge tool between the phasers tensioning them together popped out, at least one of the cams rotated back, and the CHAIN on the phasers moved clockwise! Oh - and the plastic J-shaped chain tensioner tool seems to have gotten scrapped and a piece (or shavings) of plastic have fallen in

Bank 1 - current state

Bank 2 - Shows we are either; no longer at TDC or seeing as the paint marks are seemingly still were they should be maybe I disassembled Bank 1 without being at proper TDC?

J-Shaped chain tensioner tool

I looked down in the valley with a borescope and did not immediately see anything, I will look more once the phasers are back on and I have more room to get in there.....

I have no idea how to troubleshoot or what my next move is.. I see this thread: https://www.chryslerminivan.net/thre...hasers.176147/
- notably the post by @dandaman - should I try this?

What I don't understand though. Referencing Bank 1 picture - the two yellow marks are where the phaser connects with the chain the top top part. 12 links between them. As you can see, both marks are still fully accessible and so Id believe I can easily set the phasers to where they should be on the chain. As far matching the cams with the phasers and chain - I have paint marks as well but there are notches where the phasers meet the cams, does this not mean it can ONLY go in one way and thus I'd still be in time?

Howdy - bought an aluminium lower intake manifold for the Pentastar 3.6.. which is plastic OEM.

First time buying something like this, turns out the casting was VERY rough. Started sanding to clean up casting, few rough marks in the runners, figured may as well port a little since I'm here (first time).
Well - I messed up and sanding oned of the runner lips quite thin. (0.8 - 1.0mm). My main concern is the lip cracking and being sucked into the engine... I.E. catastrophic failure.

Concerable facts;
* OEM manifold is plastic - this is an upgraded aluminium version
* Thinnest wall is ~ 1.0mm with a very small spot reading 0.8mm
* Lip thinning is at the intersection of the upper manifold
* Upper manifold runner are smaller and thus obstruct/block the lower manifold runners (I am planning on porting these to potentially flush with lower manifold)
* Runners will be sanded to 600 grit + light polish
* Engine is NA but I am planning on boosting @ ~4-6 PSI
* AI is telling me, I'm probably fine, but if I'm I paranoid I could reinforce the walls externally using JB Weld

Not really sure what to do at this point, I'm planning on sanding the rest to match and sending it. With the thinning being on top I could at least pull the upper manifold and monitor it closely for cracks... what would you do?
