Re: Head Removal
As a precaution, I would get the engine on number one cyl. TDC (Top Dead Center) as a starting point. Use the Timing pin, you'll see it down by the crankshaft pulley. Unscrew it and reverse it. When the engine is at TCD, Number1 compression stroke, it will fall into a dimple on the cam gear. Use the crank to bring it around, not the starter.
The hard part about removing the distributer (sometimes) is getting it out of the head. There is a 3/8 X 24set screw on the edge of the head between the exhaust manifold and the head that must be loosened and backed off first. Then the distributor must off lifted straight off for a 1/4" Do not try to rotate it! It is on a locating pin and has to be lifted off first. Once it's clear of the pin you can rotate it. The distributor body is cast iron and will crack if too much pressure is used. Squirt a lot of WD 40 or whatever your favorite bolt loosener is and let it penetrate say over night if the distributor is stuck. Just keep working it, it'll come!
Take a look at the crosspin slot on the distributor shaft. You'll notice it's slightly off center. This is so it can only go one way. Good luck!
