No.
Machining of the spigots is required. And you would want to add piston squirters and do oil bypass mod. I would also modify for late chain boxes as well. I actually have one on the shelf ready to go!

(Original intermediate shaft can be retained but never a bad idea to machine for bearings so that a late shaft can be used.)
