The company that is meant to be working on my 885 head say they can't find replacement valve guides.
I see they are no longer available from BMW.
Bimmerheads do them https://bimmerheads.com/products/m20-st-guides with 13.25 mm OD.
VAC do them https://store.vacmotorsports.com/vac...m20-p1659.aspx with a choice of sizes.
ECStuning seem to do two sizes https://www.ecstuning.com/b-canyon-e...121267676~cae/
Where do you usually get guides from, and how can Bimmerheads only sell one size? Which is 0.25mm oversize going by RealOEM https://www.realoem.com/bmw/enUS/sho...diagId=11_4377
