A few extra tips here Bill.

1. Unless you have studs (instead of bolts) to hold the valve covers down either don't fill the engine with coolant or drain the level down ….. the top row of valve cover bolts go into coolant passages.

2. With the valve covers off (you've had to pull the plugs and tubes) put you finger over number 1 plug hole and turn the engine over until you feel it coming up on the compression stroke then finish rotating until the timing parks line up at TDC. Mark the location of the distributor rotor and housing and pull the distributor.

3. With the distributor removed you can look down the hole and see the intermediate shaft. You will see the slot the distributor fits in, mark its orientation and walk it out with a screwdriver and magnet as described above.

4. If the exhaust is off make sure there are bolts in the upper row of exhaust bolt holes .… these go directly into the head where the oil will collect and run out onto the floor if nothing is filling the holes.

5. Unless you heads have been equipped with the press-in sparkplug tube seals (these press in recess where the plug tubes fit and provide raised area to prevent the oil from collecting in the plug recess) you will want to wad up some small rags (I normally use a single sheet of paper towel per plug hole) and stuff lightly in each spark plug recess). This will prevent oil form the rockers from filling the cylinders.

6. Prime the engine using your drill motor and turn the engine over in small increments with a breaker bar until all the rockers are oiling.

7. Before you put the valve cover back on bring the engine back up to TDC compression and reinstall the intermediate shaft and distributor according to your marks. (you might need to use a LONG screw driver to turn the oil pump shaft to get the intermediate shaft engage).

Hope this helps
