All the timing tools are in my basement and are gonna stay there, but you can make one easily with the 59A's own distributor. take an old rotor and affix something like a cat food or tuna can, painted white, to the rotor so it turns concentrically and with its rim close to the distributor. Find the correct adjustment point for each valve by any of the popular methods and at each draw a line in the can marked with the location of each valve, like "#1 intake" at something on the distributor like the steel tab on the rim. Now you have a permanent tool.
The clearances are right in your owner's manual in the specifications section. Note that the lifters are called "valve pushrods" in Fordspeak.
