Speedmaster Small block porting tips and results Part 1

I used to rough in heads for a reputable race engine builder. He’d never let me do the short turn.
I was showed where on the roof, outside wall, etc.. He did the short turn and chamber work normally.
There pretty secretive about some areas, plus it’s pretty easy to screw up the short side.
What used to blow me away was all the work involved to get a 906 head flowing 290cfm maybe 300 max wedge window, raised roof, blowing through the roof of everyone of them, and epoxy it. Done.
Now their is a ton of aftermarket choices.
