Don’t you mean the usual 3.8 B-type Metallic-Mid-Blue coloured-head, and not
‘turquoise’, albeit there may be traces (albeit unlikely) of the usual 3.4
B-type duck-egg-blue/green head colouring somewhere not evident in your
photos.
If as you suggest this head started life as a C14956 (quite feasible) then
it was originally made/intended/used on a 3.4 litre (non-S) XK150, 3.4 litre
Mark 1, or 3.4 litre Mark 2 - all the same apart from any Engine Number
stamped on.
But as per photos, the cast-in part number now shows C14958, with last digit
‘8’ stamped in, which suggests to me that this head may indeed be simply a
factory reworked/reconditioned head (pre-delivery, warranty replacement,
spare-parts replacement) originally used/intended on a 3.4, but now
reworked/renumbered/repainted Metallic-Blue to be used on a 3.8 litre
(non-S) XK150, Mark IX or 3.8 litre Mark 2.
You don’t show any HEAD NUMBER stamping, which would reveal more.
And you don’t show any CAMSHAFT Numbers, as per your inquiry, albeit CAMS
are and were regularly changed.

Subject: [xk] XK150 3.8 litre B type head C14958
I have just picked up a wonderful unmachined uncoroded 3.8 litre XK150 head
part number C14958 the 8 being handstamped meaning there was a different
part number under it ie C14956 the 6 being removed and the 8 hand stamped.
This had come from a low mileage XK150FHC What I was interested to find was
the part numbers on the cams and they were not what I thought they would be.
Does anyone have any info on the part numbers on the cams in their genuine
3.8 litre XK150 with the turquoise coloured head?.
