Subaru actually did a very good job with the gaskets. There is very little that needed to be ground off. Most of the work was done to eliminate the casting marks on the ports.

The intakes and exhaust doesn't need gasket matching on a 08 WRX; D25 heads. If anything you're better off blending the valve seats to the port runners. Don't waste time on the injector area. Casting marks are not going to make or break 400whp.
A turbo in the area of a gt3076r size with some simple 264° cams will give you a great powerband hitting the power you want on pump gas.
