took my head to a machine shop and they said i needed an oversized valve guide...because the guide that was in there has been knurled to fit, but it still slipped out...now has anyone heard of an oversized guide so it could be pressed in?

 

I suppose you could get them, never seen any for sale on the web though.
I have heard of guide sleeves though, where they bore the guide out and fit a new sleeve in it. But if yours is removed it's too late for that.

 

anyone else?

 

never heard dude. bronze valve guides are the only upgrade professional builders do.

 

Yes Ferrea makes bronze valve guides w/+.002 od's.
