Need the standard (oem ?) Solid Lifter Seat cup Height spec & How it's measured for direct replacement reusing my stock solid lifter application pushrods. My current solid measures about 1.63" lifter face to cup seat lowest point. I'm seeing popular brand various height seat specs with some referenced using a 5/16" ball ?? ...I want to use Trend's .904" non-coated Tool Steel flat tappet lifter but don't see the seat spec. Do all replacement brands use the same measurement method for '69 Big block & Hemi direct replacement ? ...Any info greatly appreciated,.....tom.
