I hear what you guys are saying and I`m definately not "hacking" away at these things but more less going by the tech archive info and straightened out the head bolt buldge for a smooth transition into the bowl. I`m not asking these questions to see who I can send em to cos that`s not in the bet or Brian would have em now.........just trying to maximize my power and 9.98 ain`t too shabby considering the other issues I had. I WILL go 9.78 if it kills me...........
