727 Front Pump Bolts

I am completely rebuilding my 1970 Challenger TA 727 transmission. Have experience with this but I just saw something I have not seen before.
The front pump bolts have shoulders on the 6 bolts and no shoulder on one 1 bolts as you can see in the pictures.
Trans looks all original and untouched but was this from the Factory?
The 1 bolt with no shoulder has a different head marking also.
Does it really matter, I just want to make sure
Thanks Bob

As long as each bolt has the coated sealing washer under it.

Head style makes no difference

Just different suppliers.

Ok, Thanks guys
