Is there a problem ? How noisy are they ? If they not too bad then I'd keep running it. I'm thinking its either had this clearance since the last valve job because the mechanic didn't know how to adjust the lash,or, the camshaft and or lifters are wearing. But I don't think these cams or lifters have a wear issue.

Mine have been at .017" for the 40 years I've owned it.

If the engine has a B camshaft then maybe the lash is OK. If I remember correctly Ford changed the B lash after a few years to .022" for the exhaust.
