Settin the valves
It all depends on the engine and valvetrain. It the engine is stock, with the original cam, hydraulic lifters, heads, pushrods and rocker arms, typically there is no adjustment for the valves. Torque the rocker arm nuts to specification and call it good. Check any decent manual, Haynes, Chilton, Motor, etc. for the torque spec.
If there are non original / aftermarket pieces in the valvetrain then it is a different story.

What heads are you using? Have the heads been modified in any way? Are the pushrods stock Ford? If not, are they the same length as stock? What brand rockers are you using? Were there any specific instructions for valve adjustment with the cam, lifters or rockers?

Again, what heads are you using? Did you do any work to the rocker arm studs? Do the heads have push rod guide plates? Do you know the length of the stock push rods? Do you know if the new rocker arms are rail, or non-rail, type? Do you know if the original rocker arms were rail or non-rail type. Are the valves designed for rail or non-rail rockers? Was the original valvetrain adjustable or non-adjustable?
It is necessary to have answers to these and a lot more questions, since the valve train is a mixture of parts. Ford used several different types of valve trains on the 429-460 engines over the years and everything has to match, or you will end up with a real expensive pile of scrap metal.
Did you have a machine shop do the work for you? Did the shop supply the parts? Perhaps the machinist can better answer your questions if he has first hand knowledge of the parts.
