Need help identifying SBM cast iron head

My understanding is the lil red engines used the “340” cam profile.
The heads that use ex rotators have really short ex valve springs, which I don’t think are compatible with the HP cam.
I have read that on the LRE cam as well. So maybe the LRE used a different cam than the police E58s?

I have a stock LRE cam beside me right now. I've looked for a part number but can't find anything.
