300e Head Rebuild what size Valve Guides?
Hi all...My 300e is getting taken apart this weekend. The headgasket blew and I figure that with 150,000 miles its time to get the valve guides redone etc. In order to cut down on turn around time at the machinists, I would like to have the guides on hand. Can anyone tell me what size guides I should be ordering? Or is it a wear thing you can't tell until you get inside the engine?
Thanks Scott

It's a wear thing and you're better off not touching valve guides that are still in spec.

Unless the old guides fell out you always go back with std guides. Even they are slightly oversize.
YES you want to have the guides replaced & the valve/valve seats refaced!!
