Re: pulling the head...
Just make a mark on the distributor and a corresponding mark on the intake manifold prior to removing distributor. Also make note of the direction the rotor button is pointing. Provided you do not turn the engine over, you can put it back together and in theory, your timing will be the same. <br /><br />But really, beg, borrow or steal a timing light.<br />What if it is off to begin with. And what if your advance is not working properly? How would you know??
