There are only 2 or 3 companies making cam cores.

You may try Cam Motion and see if they have the cores. If not, they may be able to tell you if they are even made.

I mean, not to be rude but how many hemi guys need what you are asking for? I've been asking for 7-4 swap cam cores for both SBM and BBM since I can't remember when and when I get tired of the laughing on the other end of the phone I just hang up. I haven't asked for that since about 2014 so they may be available now.
