Someone may have an old GK catalog stashed away somewhere but, failing that, there are a few options. You could locate a shop that has a computerized camshaft analysis package. One of the machine shops I do business with has a "Cam Doctor" system that can rotate the camshaft on a fixture through a complete cycle and produce a printout of each lobe profile. If that is not an option, as a last resort, you might consider mocking up the shaft in a short block and graphing it the old-fashioned way, with a degree wheel, pencil and paper. It would appear that the numerical identifiers you have located are references to particular intake and exhaust lobe profiles that have been ground onto this cam with a 109 degree lobe separation angle.
