LA intake magnum head questions

the magnum intake use a vertical bolt ......the LA intake flange is on an angle.....screwing a bolt straight down into a face that is at an angle will also need some kind of slanted washer to fit under the head of the bolt.

if you look at picture of the magnum intake or the crosswind intake you will see a boss that supports the vertical bolt....

here is a picture of a crosswind...you can see how the vertical bolts are supported.
