Mostly to reiterate what others have said:
The distributor rotor turns clockwise when seen from above.
The cylinder are numbered 1-5 from the front.
The firing order is 1-2-4-5-3, as indicated on the head.
At TDC by the crank, the rotor will either point to the #1 plug wire or
180 degrees away from it.
To get true TDC, the "0" mark on the flywheel (crank locator) will be at
the straight edge in the hole in the bell housing, and if you remove the
oil fill cap, you will see the front two cam lobes both sticking "up"
symmetrically perpendicular to the plane of the head.
Put the #1 wire there then proceed clockwise with #2, 4, 5, & 3.
After reassembly set the timing to about 6 degrees BTDC for stock
Then, since your backfiring will still be happening, fix all your vacuum
Finally, I dug out, tested, and offered to sell to you a good used
coolant reservoir (and radiator fan) many months ago. You did not
follow through and I put them away.
All the best,

I tried assembling it like the old one and it continues to hesitate and to back fire horribly. Which is why I changed the plug wires in the first place. The timing is still all off.
