In inches please and I exact dimensions. I just need the opening where the intake bolts on.

The factory ports are 2.575" tall and 1.255" wide.

Are the LS3 the same size?

Yes they are. We see the major differences between the L92 and LS3 heads in the exhaust port cores. Technically we've seen the best as cast intake port cores belong to the 5364 castings, though the differences are subtle.
