The original cast exhaust seats have to be ground out, and new hardened
inserts pressed into place. The intake seats don't have to be altered for
unleaded, and since they are so close to the exhaust, it's best to not try
to put inserts in them.

Lord give me the strength to fix the things that must be fixed,

and the wisdom to know the difference !
