Understood. But you've already complained about the bad luck you've had, and the bad results you've achieved on your own, and you've already expressed a lack of confidence and lack of knowledge about the rebuild process. This is not coincidence.
However you take it, I would rather give you a reality check now than spare your feelings and watch all your work and money go down the drain later.
Basically, you're trying to do things that really belong in the hands of professionals. Believe me, I've done enough shade tree work to know that you can get away with a lot, but replacing valve guides and reaming them correctly is not the kind of thing that is easily or correctly done at home. They should be pressed into place, not hammered. Machinists have a box full of precision valve guide reamers that are made specifically for that purpose, built in a series of finely graduated sizes to get a
precision fit. They have
very precise instruments, and they use them to measure
everything constantly - before, during, and after any process. They can measure the inside diameter of a valve guide in less time than it takes me to tie my shoes.
I am not trying to rain on your parade, but carrying on stubbornly without proper tools and training is a recipe for guaranteed failure.
If you still insist on doing everything yourself, see if you can take a machine shop class at a local community college. That's a great opportunity to get a real feel for what is required, and do a little work for yourself, with all the tools and instruction you need.
