SS big block commonly run over .800 lift and utilize every trick in and out of the book to achieve the performance numbers mentioned. I was a bracket racer for more than 30 years and I can tell you that in most cases open chamber is easier to make hp with. The 049 and 781 open chamber oval port heads can run really strong with an upgrade to 2.19" and 1.88" valves and short side radius work. The late great John Lingenfelter proved this many times.
