AFAIK, yes; I have the last PO's records covering about the last five years, and it was mostly oil changes. No smoke, minimal drops on floor of garage.
I'd guess I'll want to do stem seals and head gasket in another year or so; the car will be laid up through Michigan's winter. Running beautifully now, and there seems no reason to rush it at this rate.
