Have you put an oil pressure gauge on it?
The knocking to me sounds like mild rod knock that disappears once you've applied some throttle.
Also, our knocking tensioner did not bounce up and down like the ones I've seen displayed on youtube. It was about 6 months old too. What brand timing kit was fitted?
Does it actually drive ok or can't you get it that far?
That red cat converter is an issue and not good for it - the cat converter is either blocked or about to melt down with any unburnt fuel that's entering the exhaust system (as previously said by another forum member - seems like a shite load).

Ok
If I understand (someone correct me if I'm wrong here) - firing order is 1-3-2-4. So 1-2 and 3-4 share spark (wasted spark system). If 1 and 4 get spark, 2 and 3 must also.

i once knocked the big main electrical plugs on the drivers side of the engine near the throttle body. some of the contacts must not have been making contact and the engine ran like shit.. Once I pushed them together all was perfect. Maybe check those plugs?

Ok, clutching at straws here -- they didn't manage to swap around the injector harness when they pulled the heads off, did they?

Have you identified where the knock is coming from yet? Use a piece of dowel, touch one end to different parts of the block and put the other end to your ear and listen. Engine must be running of course!

Ok, so we now have a reason for the knock.
What are you looking into for the misfire issue on those 2 cylinders?
Spark leads the right way around?

Alright. Got some good things there like healthy compression
The two cylinders that aren't firing, are they same side or opposite/diagonally across the engine?

to reiterate...
You're saying 1 and 4 fire, but 2 and 3 don't.
EJ wasted spark setup says 1 and 2 share a spark, as do 3 and 4.
Which suggests spark system (plugs and coils) are all ok.
Maybe the cam sensor is rooted? Check the sensor, plugs, wiring and wheel for damage. If you can, stick a CRO on the cam sensor signal and check its ok.
Are you getting any fault codes?
