Depends on application, as the 12G940 was used for all sorts... from Coopers to Turbo's

I'll dg through the manuals as I think there were only a few variations...

Here's what I've found...

Coopers used 1.41" inlets and 1.21" exhaust

look like most other applications, GT's turbo's etc, use 1.3" inlets and 1.15" exhausts

MG, and Vanden Plas metros had

1.41" inlets and 1.15" exhaust valves ;]

P.S. the 1300GT and some other car also get the cooper-size valves!
