Not Ranked
Most FE cams have zero lash, they are hydraulic. As for mechanical units, If you are using an exotic alloy or aluminum valve train I would say first refer to your cam and or valve train company for specific data regarding your equipment. That said, on all carbon and stainless steel valves yes, you can use a Ford guideline of .025" (hot). Hot is described as 30 min. of idle (no load) .
Other sources will give you cold adjustment specs. Cold adjustment will give more lash to compensate for thermal expansion but may tend to be less accurate. Error on the side of caution in either case. It is better to be a few thousands loose than a hundredths tight.
