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.

Similar here. I have the ProMaxx shocker heads (same head as seen here, just bought bare and machined on here in the U.S.) and wondered if I couldn’t just simply nudge the head along some. I PM’d PPR yesterday about the use of copper tubing and while he said he used it before, the copper was much much easier to use. So brass pipe it is for me! Thought I’d share that info. Even though he may have said that before, IDK, but here it is again.
