Question Do I need 135 degree boots or 90 degree, with a big block chevy ?

Have headers, but didn't know if bbc's had the wires under the headers or over or what? straight boots seem to want to rub my header tubes..........

I,m running Dyna-max headers and ready to buy wires. I thought about using 90 deg. boots and running them behind the headers for a neater look. Has anybody seen this done?
