You are referring to the rocker adjustment or valve lash.

Gasoline 360, no. Rockers are pedestal mounted, bolt torqued to 21 FtLbs.

Diesel 5.9 yes. Valve lash should be done cold, intake .006min-.015"max
exhaust .015min-.030"max

Give a man a match, and he is warm for a short while. Light him on fire, and
he is warm for the rest of his life.

How often should this be checked/adjusted? ('03 HO) Couldn't find it in the
manual.

The 24V's were 100K... the HPCR's are at least that. Of course, it never
hurts to check 'em early - as some have reported finding their rockers a bit
on the 'loose' side of the spec.
