Speedmaster heads for SBM

I know Chris really well, we are friends. He isn’t just a class racer head guy.
He does heads on an NHRA fuel funny car, and tons of other stuff.
His whole world is smaller and torque and velocity. He apply’s it to anything he does.
Different…maybe.
my whole point is guys get ground up on here all the time for having an opinion ( speaking of the Dan guy in this thread) that doesn’t sit well with the experts on here.
I am not an expert about anything, I readily admit it. But teach, don’t kill guys. Damn.
