Amateur night - Cracked valve guide guide, oops Options

[fraggle00]

OK, first lesson, if you get frustrated - STOP and get back to work later.

Now that I've learned that, what I can I do about this:

I drilled my hole a little off-center for my intake valve guide removal ('75 2.0). Now I've got two problems

1) When I tapped the guide hole for my bolt, the threads bit into the sidewall of the head a little
2) Due to this, threads in the guide were weak and tore out
3) Got a little furstrated and tried an alternative method of banging out the guide (IMG:style_emoticons/default/headbang.gif)
4) Bad idea as it expanded a little and cracked the head down near the intake port. I quit right away at that point and found a better alternative method. I also scarred the valve guide hole a little.

Question is: Is this repairable? I can't be the first one to have done something this dumb. Of course, the guide I knocked out went great, as well as the both exhaust guides.

The '75 2.0 heads (for a very short time) used smaller diameter intake valve guides, so I probably could have it machined up to the next size, but I'm not sure what would happen down in the intake port.

Experts??? What's the opinion out there?
