To do the compressed air method is much cheaper, but are the valve guides not shot as well when the seals goes?

Not necessarily. What is causing the blue smoke is the seal being worn out. Oil is basically getting past a rubber part. I mean if the engine got past so many miles before the seals blew, theoretically, just replacing that seal would give you that much more life. There is probably a manufacturing flaw somewhere, but how much do you want to spend to find out. If you were to pull the heads, and do a complete head rebuild, then that is a different story.

Does anyone know if you can do a valve job on these heads? And where would one get a tune to compensate for the air?

Let me stir again!

If you go ahead and replace the valve stem seals, do you buy again the useless original OEM seals, or can you go after market?

Any specific brand?
