I suggest you not worry about it untill you blow a headgasket. Changing them now can be seen as either:
A: Cheap insurance
B: $95 down the tube along with disturbing your good hg seal and CAUSING it to blow.

Thats pretty interesting.... well, if your car hasnt blown to smitherines yet then, I guess my 05 EVO should be good to go as long as my tuning is good as well...
