Deena,
Use the same intake & exhaust valves regardless of unleaded or
leaded fuel.
Most machinist will know to replace the bronze exhaust valve seats
with a harder material, like Stellite. OEM, bronze, intake valve
seats are fine as they don't have to put up with the heat like
exhaust valve seats do.
Cheers,
Tom
