I'm familiar with the Brazilian cut myself. They have always given me a longer push rod when working on themI dont know why everybody is so worked up with the lengths and measurements.
If I was building engines for midget race cars I could see getting worked up about the length of the pushrods. I would probably want shaved the heads for an extremely tight too. I even heard some talk about Brazilian engine blocks for those wanting more than a shave.
All the midget engine technology stuff.
