Well, FWIW, I ordered standard guides, since my guide bores were in spec. Luckily I ordered a couple extra.

Turned out that half the guides I received were over size by a couple of thou. Long story short, I had to machine several of them down to the correct fit. Some guys will machine every guide to a perfect fit.

If you have a lathe, it is really no big deal to machine them down.

BTW, the original Porsche manuals say to use tallow for the install lube. Sun makes a valve guide lube, which is tallow based. I cooked up some bacon and used the grease, which is basically tallow.

If you read the Carrera manual, it says to use talcum.
