From what I have read, you have to cut the firewall to make it fit.

That issue was the one that bothered me least. The finished cut and re-glass or tape cover actually winds up looking stock.

The LS2 fuel rail mounting holes don't line up. You need LS1 injector o-rings. The airbringe needs tweeking to fit since the manifold fits farther forward than the stocker. The supplied throttle body bolts aren't long enough.

We reshape the area at the rear of the intake manifold and leave the firewall unmolested.

When I called them, they had no plans of making one. The mod to the firewall is 3" X 2".
