Speedmaster Small block porting tips and results Part 1

I’m good at derailing but being that TrickFlow cast their own heads and they are a different casting I wonder how much meat is left to work with. Slightly over 300 with a 2.02 valve and a 190cc runner. My set that flows 315-318 has a 2.08 valve and a 191 cc runner. Just thinking out loud here. Hmmmm.
