Given where you live and the mods you are chasing you will need both.
Bolting a GT35 onto stock heat exchangers is really going to strangle that turbo.
Intercoolers are free horsepower, however that extra power does not materialize until the engine overtaxes the capabilities of the stock unit. That will occur when you get into heavy traffic and heat soak, or on a hot summer day, or when pulling boost for extended periods. It is simply not possible to accurately measure the effect of an intercooler on a dyno, the car must be running down the road with all the aerodynomics in play. Shrouding is essential.
If I were in your shoes I would add a larger intercooler now before summer and add headers this fall. Once the cold winter air hits you'll be looking for new rear tires next.
