Anyone ever run Speedmaster Heads on their small blocks

What head do these flow number belong to?

Is there flow number out there for the shocker?
Claims 285 but is there a full lift swing of the port somewheres?

Flow Data @ 28″ water
lift 200 300 400 500 600 700
Int 142 202 251 278 284 286
Ext 124 159 190 203 219 231

You asked about the Shocker 185, there’s the flow numbers from there site. I should have labeled it!
