Speedmaster Small block porting tips and results Part 1

You guys are going to know more about head porting than my 31 year old son does. He’s raced since he’s been 16 and can build an engine, but has zero interest in head porting other than he want me to port his heads. Lol. I keep hoping that this changes before I either die or get to old to teach him.
On paper, leave a link to this thread, just incase.....
Leave it with the wife, where he can find it later.

And threads like this, we can use, in a big way!
Mucho THANKS!
