Sounds like they are the older 190cc port. I have a set on my 385ci. While not as good as the newer Eliminators they still outflow and make more power than the other heads out there with the same size ports.

I had a Lt1 AFR 190LTS and they where the old castings,i´m not sure with these

If they where 210cc what would the marking be on the head?

The 4 digit AFR part number will be stamped into the front face of the heads where your accessories bolt onto.
