Was that after valve work? The valves on my last set were seriously recessed (unleaded syndrome) and needed new seats. But I imagine that changed the volume a bit.
Yes, I had them ported with 1.88" intake valves and 1.60" exhaust valves that I got from an old set of 360 heads, fresh valve job with hardened exhaust seats, then a clean up on the block face to true them up....
