Default Phase I 2.5 things to look for?

well, now that I have gone from the indestructible SOHC 1.8L to the DOHC 2.5, besides head gaskets, what should i look out for? and If i get on the throttle once in a while, will this make my HG's go sooner? the car has 209k miles, so am I safe to assume the HG's either won't go or have already been done? I love the car, but i don't want to romp on it and look back to see a cloud of white smoke.

Other than the headgaskets, you'll want to listen carefully for piston slap and slight rod knock. Piston slap is almost inevitable given the age, and rod knock wouldn't be surprising to hear about.

Other areas of concern would be:
Backing plate of the oil pump, check it for screws that have backed out or are just loose.
Oil separator plate on the back, check it for leaks and replace with updated steel piece.
Timing belt tensioner, check it for proper operation along with all the idlers.
Water pump, check it for leaks or other signs of impending doom.

Replace any or all of these items if there is any doubt to the condition.
