Mcgurk Chevy ii camshaft help!

I have found a couple of old mcgurk camshafts for thisittle banger I'm gathering parts for and I'm trying to Id them. Here is what's stamped on them:
292-5 296-6 g 2284 on the first one the second one just has 292-6 on it . I've tried calling isky several times but can't make contact with the guy who may know. Can any of you guys let me know what I've got here I'm about sure they are either roller or solid lifter cams as they came from a midget racers parts stash
