The big 100!

Ok well my car isnt there yet but it is getting real close. I am coming up on 100k! in my 98 galant. Is there anything i should check or change? like gasket, pulleys, or anything? I havent had the car the whole time so i dont know at what miles he changed stuff. I do plan on doing the 4g63 head swap by 100k with some 646 intake 672 exhaust cams(getting them brand knew hks for 50!!!!) I plan on using adjustable cams and new valves. So is there anything i should check out or just keep on doing the usual matience and rutine checks?
