Re: valve guide?
This is usually a machine shop job as the new guides need to be honed to size and a valvejob performed...
There is a special driver that works with an air hammer/rivet gun that Snap on makes. I think its a 5.5 mm.
Clean the head really really well. Pressure wash followed by a round or 2 in the dishwasher works pretty well.
Next set your oven to about 175 degrees. Bake your head for say about 15-20 minutes.
Remove the head and place on a good flat non marring surface.
Knock out the valveguides with your air hammer and driver...

Installation really needs to be done by a machine shop,
Good luck!

Re: valve guide?
Its really not that bad...
You just get the head hot (Up close to operating tempature) and knock them out with the correct tool. The extensive cleaning beforehand is to keep the burnt oil smell out of the oven assuming you cook food in yours.
But yeah if your not comfy doing it yourself, definately take it to the machine shop.
Its not a bad idea to let them completely build your head from start to finish. Good luck!
