Hi All!

I have been going through my collection of Mini parts and have come across a complete rocker assembly.

The numbers on the individual rocker arms are: 12G1222

I am not familiar with this type of rocker and I have a hunch it may be from a Cooper S. If it is, I hope to find the rest of the car hiding in my shed

Am I right, S stuff?
What ratio?
Worth much?

Thank You all for your help.

Regards, Lindsay

Yep 12G1222 are Cooper S forged rockers.
They are stronger than the rest but have poorer lift.
When I checked their valve lift with an RE13 cam and 1275 head I only got 1.16:1.
Sintered A+ ones were 1.18:1.
Pressed steel 850-998-1098 ones were 1.21:1.
All checked on the same cam lobe and head.
