You actually want to leave a satin finish on the intake side of things, a mirror finish doesn't flow as well (ask NASA) due to the missing mini-eddies that increase the velocity of the central mass of air.

Gasket match. Enlarge the holes for the upper/lower with say....a drill bit and then use a sharpie and lay it on the manifolds, take out where it marked areas. When you put them togethere they will line up juuuuust fine.....

you can trim the gasket to the port size of the first part and then stick the gasket on the second and grind so they match. you can also use a piece of paper with the same procedure.

I use a scrib to make my holes....
jeep is close as you don't want a slick mirror finish is because of them being so slick the fuel and air don't have enough time to mix well..on a near stock car just gasket matching is all you need..using a 1/2 spacer between the uper/lower in take will help with heat and allowing a lil cooler charge
