Speedmaster Small block porting tips and results Part 1

My point was to show how nice a port can look but give you a kick in the nuts on a Flowbench. Lots of sleepless nights and ruined heads cutting down the shortside in search of area.(the wrong move) 280-285 is what I expect to see before I’m done with a 2.02 valve. On topic that hasn’t been touched on much and I would like to hear more on is throat sizing. I think it was 318 that gave me his throat sizing on his cnc’d heads and it was a lot bigger than my bare heads. Did anyone else do anymore checking on this. I may flow the stock exhaust if I get some shop time today but it’s a total waste of time. The exhaust port is just plain ugly out of the box.
