Do you mean there is only 2 notches left to take up the slack on the chain or 2 notches from the front of the tensioner where it pushes against the guide or 2 notches left in these in the tensioner? 2 from the guide side is good 2 notches from the back is bad.
There is a some stretch on the chain as the dots are behind the cam cap marks.
Rotate the rotor counter clockwise until the marks line up again and check it the marks stay the same and do this about 4 more times and see if there are any changes in the line up. if there is any change the chain has tight spots which may be the cause of the slight rattle you say you have.
With the cams in this position you should be able to slide the feeler guage in between the cam lobe and bucket over the valve on the 4 valves on the 1st cylinder . See example in page 3-6 on of the manual
Rotate the rotor counter clockwise 180degrees and you should be able to check the clearance of the no 2 cylinder
Another 180 and check the no 4 cylinder and a further 180 check the no 3 cylinder
Valve clearance (cold)
Intake valve
0.11 0.20 mm Ideally the 0.11 should slide in nicely and the 0.20 should not slide in. If .20 slides in easily there is to much clearance
Exhaust valve
0.21 0.30 mm Ideally the 0.21 should slide in nicely and the 0.30 should not slide in. If .30 slides in easily there is to much clearance
What you are doing is really ruling out causes of the noise.
I presume you check the downpipes for small holes which can give really funny sounds
