They don't work.
The distance from the pivot point to rocker tip is different from a Pontiac rocker.
Topic of interest. (http://forums.performanceyears.com/groupee/forums/a/tpc/f/6406082911/m/4736025911/r/4836025911#4836025911)

For those who care- probably nobody- small-block Chevy rockers will work on '55-'58 Pontiac heads, if you choose a pushrod length which gives correct geometry.
