Borla header gasket

I'm about to port&polish the 94 head I have and was curious about the larger gasket that came with my Borla header(it came with one reg size and one for larger ports). Did your Borla header come with two gaskets as well? Has anyone used the larger gasket? Has anyone port matched to the larger gasket? Basically the exhaust openings are 1 7/16" and the intake openings are 2 1/8" x 1 7/16," so holding the gasket to the head I can see 1/4" all the way around the exhaust ports and a 1/2" on the bottom of the intake ports.
