You might want to retard the timing a few degrees (about 3, ISTR, from a 98
octane setting) depending on what octane rating they give you. Ours is 95
octane, whereas leaded 4* used to be 98.
as to the lead... you might be OK with an '85 engine. I think it's only
early ones that are prone to damage, and not all of them - being an alloy
head, it already has valve seat inserts. The biggest problem engines are
cast-iron heads with the valve seat machined straight into the iron.
