I have just completed gas flowing the head and rebored the cylinder.
I Had to travel all the way to Bombay to get the job done properly. I have replaced the valve guides with phospher bronze guides, the new inlet valve has a larger head than the stock and the valves are nitriled.
We have also cut the seat to unshroud the valve(three angle valve job).
Monster Dog should should be ready to fire up by the end of this week!
