1970 340 "O" Head Casting Nimber and Date Code

[Fastvaliant68]

I have a 1970 340, the heads are "O" casting and have the casting # of 341891 a bit of a space then a B. The date on one side is 11129 and the other is 11179 also castin AAWJ and 360. My question is are these 3418915 heads. From the date code I am assuming the were cast Nov 69 making the correct for this motor. The block casting date is 7-10-69

Those are the heads a 70 340 would most likely come with.
