Raising the sleeve with modded headshims does change intake and exhaust timings, it is a thing anyone can try and it can also be undone.
I find it interesting that every engine modder claims to be able to achieve more power and in some cases, more mileage. So if I mod my RB C6, I can make it a better engine than Rody designed? If modding was so across the board good, that would seem to indicate that people who make a living designing engines may not know what their doing? Just saying.
Fanging and turbo cuts really don't help that much. I would think the changing of crank and port timing would be too much for most people. Takes the right tools and experience to beat Rody at his game.
