Speedmaster heads part 2. Plus intake work

This was the best technical thread still active right now with the kind of hands on work I like to read about. I bought a set of the these Speedmaster bare castings just to see if I could accomplish some of the same modifications without screwing them up too expensively.

I will continue to refer back to this thread and your previous one on these heads, so I really appreciate you posting all this great information. Thank you pittsburghracer for all the time and effort you spent on this.
