Oversize valve guides
« on: 01.07. 2019 16:07 »
Hello,

Stupid but easy question here: I take that oversize valve guides refer to the outer diameter, and is meant to accomodate for wear in the head?

yes - for some engines used to be able to buy OS guides, but I guess we have to make our own for the A series.

Hi All

Usually only needed for the alloy head
