Thanks

I saw a few webpages on this but I can't recall them... They said you got to drill them out with a drill press and insert new ones with a special drill and a special valve guide inserting bit which will cost a ton... plus you need telescoping micrometers to make sure that yours are out-of-spec and that the new ones are in spec... IN CONCLUSION: go to your local CNC shop or metal working shop and see what they can do for ya....

yeah after a bit of googling that was the conclusion I came to myself. Atleast I was able to clean the head up a good amount..
