Cylinder Heads on a 383

[4aThrill]

So repainting the old beast again,and looking more close at the numbers on the cylinder heads: the left head has 3462346 and the right head has 2843906-6 thinking to myself hmm thats kinda odd different numbers is this a common? any thoughts?

never had a problem in the past on how she ran or anything.

3462346    383/400/440    1971-72    2.08    1.74

2843906    383/440          1968-70    2.08    1.74

Valves are the same, but what about the flow?

when I had it rebuilt in back in 2003 the machine shop never said anything, and again in 2006 when I got a 3 angle vlv job on the heads so, any info on the flow?

The flow from both of those heads will be very similar so it's nothing to be concerned about 

Both are open chamber design with approximately the same combustion chamber & port volume
