ok so far i have reemed the guides no chattering with reemer, and valve slighty falls with its own weight lubed. I have a full set of newell cutters as i use to be in speedway and play with my own head designs.When you put your cutter sharft in it expands in the guide i will cut the seats at 46" and cut back to make seat 1.8mm width.Man i do not even have a sucker to fit this small valve but i am likeing the no heavy lifting of engine parts.
cheers nick
