small block 974 head

[teringer]

I purchased a set of the Indy rebuilt cylinder a few years back for a 340 with the only thing done to them was the 2.02 intake /and 11/32 dia. stems the heads were the 974 casting so I've been on line looking for stock or ported heads with the same numbers for flow ratings I have found lots of good info for all except this casting the 974 why no listing? they look like any other head ,does anyone know about this head ?

The 974 is a J casting, but is different than earlier J castings, the 915s.

It came out around 1974, large intake ports but the smaller intake valve.
