Had a buddy who ran those super commando heads in a bracket car with a stroker and 904 few years back
They had been fully ported by a reputable guy most on here would know.
Plenty of compression, roller cam, etc, etc
Never ran as good as i thought it should. Struggled to break 10 flat in a roughly 3100 pound car. Ran around 130-131 mph in good air. Usually 10.0xx something
Not that impressive for what the combo was in retrospect. Hsd a good bit of money and effort in them
