9/16 to 11/16 valve

[sandfreestyle]

Pardon my ignorance, but what does it take to convert a 9/16 body to 11/16? Is it just the boring? Does it still use a jam nut?

yep drilling and reaming through the existing valve to the spring support wall.

Does it still use the jam nut or just the set screw from below to hold it in?
