Ok, when looking at the engine bay from the front of the car, the cylinders on the right (driver’s side) are numbered as follows. The most forward is 1, then 3 then 5 and then 7. On the left ( passenger side) the most forward piston is 2, then 4, then 6 and then 8.

Turn the engine with the plugs removed (if you can rotate it without removing them, then that is fine) but do not rotate with the starter, just in case you already have a few valves adjusted too tight.
Firing order is 18436572
Rotate the engine and watch for the #1 exhaust valve to open half way, then adjust the intake valve on #1 and the exhaust valve on #6.

Next, rotate engine so that the #8 exhaust valves opens half way, then adjust the intake valve on #8 and the exhaust valve on #5.

Next, rotate engine so that the #4 exhaust valves opens half way, then adjust the intake valve on #4 and the exhaust valve on #7.

Next, rotate engine so that the #3 exhaust valves opens half way, then adjust the intake valve on #3 and the exhaust valve on #2.

Next, rotate engine so that the #6 exhaust valves opens half way, then adjust the intake valve on #6 and the exhaust valve on #1.

Next, rotate engine so that the #5 exhaust valves opens half way, then adjust the intake valve on #5 and the exhaust valve on #8.

Next, rotate engine so that the #7 exhaust valves opens half way, then adjust the intake valve on #7 and the exhaust valve on #4.

Next, rotate engine so that the #2 exhaust valves opens half way, then adjust the intake valve on #2 and the exhaust valve on #3.

One last thing. Rotate the motor where the timing mark is at 10 degress advance with the #1 piston valves both having been closed for the up stroke (compression stroke), set the ignition rotor to the #1 wire on the cap or rather turn the distributor base so that the #1 wire will line up with the cap, and wala. No back fire, just music.

Someone please double check me on this.
