Top 3: cooling system maint, repeat, repeat.
If you have not replaced the OEM rad cap with the revised MC cap, do so at once. RS-527.

If you keep the cooling system maintained the engine will never overheat and never crack or warp the heads.

Vulcan heads are no more prone to cracking / warping than any other engine.

With Chart and Jeff, keep the cooling system maintained. Never once heard of a head fail in a Vulcan that did not involve an overheat.

If your ever at the upull yard, you can tell a overheated Vulcan by all the brown sludge
in the degass tank. If you see that you know the coolant is compromised and it has
either overheated or it will.

There also is a possibility of head damage from pre ignition or knock. Some Taurus are prone to it due to errors in the octane settings in the PCM. I believe one of my 2001s with 166k miles may have a small crack in the spark plug area. It maybe leading to a sporadic and infrequent misfire on #3 cylinder. It always had a spark knock for years.
