Resolved - BC2945 Valve locks, despite saying 6mm stem diameter, are compatible with BC2200 retainers because the exhaust valves taper to from 7mm to 6mm at the lock/keeper groove. Confirmed with BC direct.
Yo,
Inlet valves on S14s are 6mm stem, exhaust are 7mm.
The car I bought came with replacement Brian Crower valves, but no valve locks.
When I go to their website:
https://www.briancrower.com/makes/ni...lvetrain.shtml
It shows the locks saying "6mm stem diameter" but also a "set of 32".
When I go to the product page:
https://store.briancrower.com/produc...ant=1609984643
It makes no reference to the stem diameter.
Presumably they're the matching locks for SR20 valves right?
