Speedmaster heads part 2. Plus intake work

Ok guys back to porting work. I usually don’t go about it this way but I wanted to show you how much I push the pushrod pinch wall back the whole way to the bowl not just at “the pinch”. Look at these pictures then in the next post how it should be. Doing this really affects how wide we can make the Short side. Keep in mind at this point just past the pinch the roof is slooping down, the floor is slooping up, and the common wall is slooping in. We need area.
