[6pack] TR6 Cylinder Head Question

[Irv Korey]

Good morning,

I am trying to identify the cylinder head that came on a spare engine that I
recently bought. The head has the number 313248 cast into it. When I go to
The Roadster Factory online catalog, that number comes up as a TR6 cylinder
head, but doesn't say from what year. Can anyone point me in the right
direction?

Thanks,
