Cylinder Head ID - Casting and Date Code

So if you go by this chart what 2.02 heads did 1971 340/275 Hi Compression 4bbl motors have?

Back to these-
3418915C
2990
AAWJ

3418915-C - if you look at the chart below the only 2.02 valve 915 was the T/A
So the date code 2990 comes out as Saturday - 10/4/1970 That would make it a '71' car cyl head
The AAWJ and the cast "J" by the plug hole confirm - J

Members stated above:
My heads do not have the T/A offset pushrod holes. (I don't know what I'm looking for as far as 'drilled offset')
Do Not have 1.88 valve size. 2.02 min (but looks 2.08 ?) Heads are not here for me to measure.

So ... what I come up with if the chart is correct:
1.88 heads -70-72 360 head or a 71-71 340 head with 'oversize' valves installed.
Or:
If the chart is wrong on the 71 2.02 heads then these are just that Oct. 70 produced 1971 340/275 2.02 heads With maybe 2.08s in there now.

OMG ...
