According to Vizard (3rd ed., p 167):
12A185 was an early "S" casting, coded "yellow." It should have 1.4"
intakes and 1.15" exhaust. But it may have 1.218" ex. The text is a bit
confusing. If it has the larger ex valves you will want to check for cracks
between the valves. It is also (apparently) a big bore head, thus not
original to your 9CG engine.

Subject: [Spridgets] Todays LBC content, question
I just bought an engine and gearbox, complete and running with all
when pulled last year, with the number 9CG-DA-H23732 and the cylinder head
I understand what the engine number means. It came from an Midget MK I,
ratio gears, high compression, 9.1. My question is that head, seems it is a
Cooper S head is it not?
