I am doing a head swap on my 97 GT. The PI heads were ported and polished, valve job including new valve seats and oil seals. I filled the cam holes with oil and was really liberal with lucas heavy oil on the rest of the cams. There is oil dripping down some of the valve which surprises me because I thought the oil seals would stop that. I am assuming everything is okay but guess I am looking for an explanation of where the oil is coming from and assurances before I bolt them on.
