Speedwell Cylinder Head Identification

[mini129]

How do I identify which model speedwell cylinder head I have.
It had C 317 D stamped in above the hole for the temperature sender.

It's a Clubman (C) head.

Thanks. I found the speedwell cylinder head section on the site after I posted the question.
Does the 'D' after the number mean anything?
The head came with the 1.5 speedwell rockers but no valve springs.
What would be a good set of springs to use other than the obvious speedwell ones?

I have a set of NOS Speedwell springs here.... (VA50.BMC)

The "D" after the head number is a batch. I have seen A through to F on various heads.

Thanks mark on identifying the 'd'. I will contact you also on the issue of valve guides.
