Mike,
You don't need to change heads to run unleaded. You can simply have
your valves and seats replaced with hardened ones. It will then be able
to burn unleaded without worrying about recession. Plus, the 1500 heads
are much thicker than a Mk3 head and unless you shave it considerably,
it will be way down on compression.
Cheers,
Joe
