Identify these Z1 / KZ cams please

Anyone know what these cams might be?
They don't look too aggressive. They def look like street cams I think.

Marked: EP14 CWC I-5
And on ends, stamped: 13043

Not sure if this will be of any help but this post has some info that might answer some of your questions

Unfortunately no, that link you mentioned does not help.

Doesn't seem to be MegaCycle.
Doesn't seem to be CamMotion.
Maybe Norris or Engle? No clue.

I'm trying to figure out if the marking of "13043" means anything specific.
The other markings don't tell me anything about what company these were ground for.
Date shows Sept 1994

The cams measure somewhere near or around .350 lift
Don't know the duration.

Anyone have any idea's what they might be???
Thanks.
