Hi Cotten,
ULP is Unleaded Petrol. That's what lead free petrol is called in Australia. Some people in OZ also run there cars on Liquid Petroleum Gas (LPG) and because it burns hotter there have been problems with older vehicles with cast iron heads where the valve hammers it way into the cast iron resulting in the need for hardened inserts.
I was wondering if perhaps the result might be the same using unleaded fuel and the original valve seats in a VL due to the higher operating temp.
Based on what you and Steve have said if the valve seats are ok I think I'll take the 'if it aint broke don't fix it' approach and leave the seats alone.
