Hello all, currently restoring a 1973 240z from Texas and just want to know if the engine can run on unleaded fuel without any issues, it has an aluminium head (if that changes anything) I know all steel heads need new valve seats but not sure on the aluminium heads
Thanks
Joe

a couple of thousand miles a year or twenty thousand?
It wouldn't hurt to take the head off and see what seats its got and whether they've got any recession already.
If you do it yourself it'll only cost the price of a gasket or so.
