My aching head!

[Bill Schleusner <b-schleusner@ti.com>]

I'm sure this has been discussed at length before, but I've slept since then.
How do pre-75 B owners cope with unleaded gas.  I know the head was changed in
1975 to accomodate unlead fuel but what do I do about a 73 engine.  Will I need
to change the valves and lifters, etc. or do I just run the engine until it
needs a new head.  Any suggestions welcome.
