Valve guide adventure

With the valve guides oxided, I decided to upgrade them. Bought a set of Supertech GDE-T4AG-SM with VS-T6SM seals. They should be 40.5mm long and have a outer diameter of 11.03mm.

Found out that Toyota has used plenty of different length valve guides in various engines while having the almost same outer diameter of 11mm.
