Default 71 350 head ID help

Changed valve cover gaskets and took a few pics, from what I see this is what I come up with, 3876487 350 71-73 1.94/1.50
Am I reading it correctly?

looks correct. if date codes are before the build date of your car by a week to a month or two, probably the orig heads on the car. other than that and paid for and work they got not much going for them. nothing special head that is about the first thing to go if you want to make power...

That would be the correct number. I have the same heads from my 1971 350. They are a good flowing head. The LT-1 version of the head at 2.02 and 1.60 valves. The biggest issue is the big chamber size due to the change to unleaded fuel around that time.
