SUNNEN DIAMOND HONE SPRING
Anyone with a Sunnen diamond hone head can gain more clearance on the bottom of cylinder to main web area by taking off the factory spring setup and replacing with the spring from a small block Chevy front cover seal. It fits perfectly in the stone slots on the bottom, as shown in the photo.
