Bit rough sketches but enough to have some made by a mate.
you can do anything if you set your mind to it...

#2 almost impossible to machine cost effectively. You’d be better off boring and reaming a hole thru the center, and adding Gtol to the end face to ensure perpendicularity. Them heat up, and press in a drill rod that is slightly undersized (or the same size as you reamed and use loctite to secure it. On 17th Nov, 2014 Tom Fenton said:

I’m not sure what #3 is meant to do? IMO the best thing to do is buy three reamers and gradually work up to the correct finished size. That is probably more likely to yield better results than this. Fact is, you can’t be sure Exactly how concentric the ID of the valve guide is to the OD, and you also don’t know how concentric the one that was in there is to the seat already cut.

Stepping up from 7mm to 7.12 MM? And for the rest. You have a strong Point. Didnt look at it that way. ( 3 was to set the reamer straight. you can do anything if you set your mind to it...

I've just fitted new guides to a head with just simple tools:

Use the hammer and bolt to knock the new ones in to the height set by the washers. Ream them out to 9/32". Hand reamers have a slight taper and will not need to be supported to get them straight. Simples. thnx. the reaming was my biggest worry. you can do anything if you set your mind to it...

Use a press to put the new guides in if you have access to one, hammering them in can deform them. 😎
