G'day Bon _Scott,
Yep, for steel rings a light hone/deglaze is OK for the cast iron bore. Not really necessary unless the bore is visibly glazed, though.

Valve clearances are the same as for the kool-bore engine; IN 0.005-0.007" EX 0.009-0.011".

By the way, this is the correct Service Manual for this 1984 vintage engine - free download for ODK members, about 5MB.
