Can anybody identify these cams?

[overfedfish]

Got a whole bunch of parts in a lot and included were these. Don't know much about SR20's and parts for them but the guy I got the parts from said they're Jim Wolf's, but he said they're not marked as such. Can anybody help identify these? They have 53J written on them, as well as an L in a circle, and 10 written on the exhaust cam.

Those appear to be Jim Wolf's, however every manufacturer except for Tomei and Nissan use the same blank cores out of Turkey so the stampings are pretty useless.
