Speedmaster Small block porting tips and results Part 1

This thread is awesome. It kills two birds with one stone. It answers alot of questions some may have and addresses the problem child in class. I started a set of speedmaster heads this spring. My grandfather became ill and passed away. I closed the doors on alot of things for quite some time. My Duster was one thing I kinda quit. Any rate my flow numbers were real weak .200-.400. Can't say for sure it will help my heads as much, but I have learned just how much these things benefit from a good valve job. Thanks PBR and PRH!
