I'm guessing that you don't have a timing light etc. It would be easier, but you can still get pretty close without the. If you take the valve cover of and the spark plug out of you number one cylinder, and slowly jack the engine over. As the piston decends on the intake, watch the intake valve open open by watching the valve stem depress. As the piston rises on the compression stroke both valves will be closed. As the piston reaches just BTDC stop. Follow the spark plug wire from the number one piston to the distributor. Gently remove the distributor cap and the distributor rotor should be aligned to the number one prong on the distributor cap. 10 degrees BTDC is a normal point, but check your manual for anything that may not be generic. This will get you very close. Return the cap, as it was. If this is good, reinstall the plug and the valve cover. Now that everything is reassembled, return to the distributor and you will notice that the distributor is held to the engine by a fork that is secured in place by a single nut or bolt. Loosen the nut suffeciently to turn it, but no looser. Start the engine. set the engine to idle. Turn the distributor slightly in either a clockwise or counterclockwise direction, but only a few degrees. If it sounds better, turn it slightly more, and reassess. If it sounds worse, however, return it the direction from where you started, and turn the opposite direction, ever so slightly. Small adjustments are the ticket. When you reach the point where you have the best sounding engine, tighten the retaining bolt, or nut. It is easier with timing lights and osliscope, but I'm guessing you don't have any.
