[Colour me gone]

Hi

I just recently bought my 3rd Porsche and had 2 3.2 cars prior. The SC of course has the 3.0.
I'm still a novice but I have a good mechanic holding my hand through the process although the basic stuff I'm all good. The car has 162K KM (97,200 mi) on it . The car sat in a garage for ten years but is now cleaned up and after changing oil plugs filters gas tank etc etc it runs all good.
The worry is what I read. Head bolts, chain tension update, and air box issue. The engine runs like a top and there is no outward concern to any of three items that I've mentioned I have a budget and want to spend it as best I can.

Can anyone tell me what order these would be done ? I drove the car 20 miles when we got it running. Then put it away for the winter I need tires and shocks and I would like to do brakes first and the engine issues next. Perhaps I'm the wrong way round with the schedule ?

Any advice is appreciated
