There are much more knowledgeable people than me on this topic but I believe there was mention of a few projects in the works with these heads over in the engine forum. However, I'd consider this more a piece of the puzzle rather than a conversion kit. To spin a 911 motor to 11k require much more than just new heads. I believe the Tuthill motor uses a custom case, crank, rods, and pistons among I'm sure many other parts.
