Can someone please tell me the

Can someone please tell me the correct firing order for each of these engines? Flywheel fwd and I understand that the cylinder numbering on both engines is from fwd to aft 12
34
56
78 correct?
I've searched the manuals I've received from the Mariners Museum in Newport News but can't seem to find this simple bit of info. If the order is posted on one of the manifolds then I just have not found it yet.
Thanks for any help you can give.
