Firing Order!!!!!!!!!

ok this is a ford 150 79' with a 400 engine , and the peoblem is the this engine has stamp on the intake the firing order 1-3-7-2-6-5-4-8 but with this firin order won't start and read a book on this truck and it is the correct order so I keep trying and for some reason I'try this one 1-5-6-3-4-2-7-8 ? and yeap ran with this but back fire!!! well my question is this 1-5-6-3-4-2-7-8 is a normal firing order? or is not?

the one it runs with is the correct firing order. the numbers on the manifold could be for a different motor. meaning a previous owner might have changed the manifold.
