Some cast-iron engines had an insert for the exhaust, but the seat for the intake was the cast-iron block.
Other cast-iron engines had no seat inserts, and both seats were cut into the cast-iron.
I don't think you will have a problem using today's gasoline. .....Most of the small-engine valve problems I have seen are from over-heating due to clogged cooling fins or being run low on oil. ....Dirty oil usually wore the guides prematurely, especially in aluminum-block engines without replaceable valve guides.
