Speedmaster Small block porting tips and results Part 1

That's kind of my thought. I bought them bare non cnc. I have never ported and probably do it but how well I don't know. So for me to pay someone $1500+ to port them and put bigger valves in them and still not flow as well as trick flows, to me is a no brainier.

I had bought the speedmasters because all I had was a bare engine block to build. I ran them before the whole hype started and I'm ready to pick up some E.T. I still highly recommend the speedmasters to anyone looking for a good head at a great price.
