I have a 'C Type' head that was fitted to a 1951 XK120 in c1952.
It was removed c1956 and stored.
The present owner of the XK would like to re-unite car and cylinder head.
How can I find out the value of this head?

It was fitted to this XK:-

Ah, the 'C' type head chestnut surfaces again! You will hear all sorts of stories now but what I believe to be the truth, and what we used to tell our customers when I was at Lynx, is this. Jaguar wanted to fit larger valves to the works XK engines but there was very little spare metal around the valves to cut into. An order was issued to the foundry to cast 30 new heads with more metal to allow bigger valves to be fitted but somewhere along the way the 30 became 300. In the event the remaining 270 were used up on production cars, some with bigger valves fitted I believe. So, does it signify that this head was ever on a C Type, no. Is it fantastically rare, no. Is it extraordinarily valuable, well no but it does have some extra value simply because it looks great on the engine. What's it worth, no idea, what the buyer is prepared to pay I guess.

I once took a call from someone who said he had an original wide angle head for sale. We had a little question and answer and what he said suggested that this was indeed that rare thing so we met in a motorway service - and it was just what he said. I paid him £17,500 on the spot and before the end of the week we had sold it to one of our customers. That was thirty odd years ago so what it would be worth now I shudder to think!

A few years back Mike I came across these in the back streets of Le Mans. As far as I know they are still there. There were a pair of sancast SU's too, but I can't find the photo of them.

There's also the 'C-type' head that was fitted to SE spec' XK140's. These are not especially rare (although they, again, do look good)

They look interesting Tony. Were there any of the shallow dry sump bottom covers there, that would add to the interest but vented cam covers is a good start! Hard to tell from the photos but the ports on the cylinder head look as if they have been fettled too. Would it be worth a trip to see if they are still there and, if so, buyable...…………..? What is the casting on top of the left hand block by the way, is it the front cover? And sandcast SUs, they are worth something now, a little treasure trove potentially!!

The F1 specialist manufacturer here did a run of lightweight blocks for a gentleman now resident in Belgium, but to stop the warping he had strengthening ribs cast on them. Thrown out by the FIA and so were mouldering on the shelf. And yes, the sumps were there. Along with a few of his cars of course. Note the dismantled GT40 on the right and my Lynx in the middle. His Ecurie Ecosse D-type was away being painted at the time.

Lovely photo LD. A good mix of superb cars.
Is that a 289 Cobra in primer on the left?
My dad had a new one in 1965, but I've been unable to trace it.

Front arch shape indicates a FIA 289 Cobra, but it's missing the hood scoop of the FIA Cobras.

You missed the Daytona at the bottom too. He signed a cotnract with Carroll Shelby to convert six original Cobra 289s into Daytonas.

Fabulous pic, I am just consumed with lust! Love the little Lotus 11 - or is it a 15, I almost bought an 11 off a mate in 1966 for £350 but my then wife objected, as she did to everything with wheels, so I didn't.

Funny you should mention a Lotus 11. I was going through an old magazine (one of many I was given 10 years ago) and this fell out:-



There are other cars missing from the photo such as his Galaxy, his Lotus 6 that was once the property of Henri Pescarolo, his Coombs Mk 2 and so on.

Does he know Fred Fairman, if not he should. Fred is THE world authority on Lotus 6s and the leading restorer for them. His workmanship is utterly peerless, he used to admire Lynx stuff and equally we used to admire his stuff. He, and his sons, are still working and we are still very much in touch, I will make the intros if your man is interested.

In the meantime, has anybody any idea of the value of a C Type head?

Beg pardon, got carried away

XK cylinder heads seem to go, at a quick glance, from £200 - £300 for those needing complete refurb up to £1500 £2000 for those that have been done and are ready to fit. The big question, and one I do not know the answer to, is how much of a premium does the 'C' casting mark command. It shows that it is an early head which I feel sure would make it attractive to owners of early cars but then what is the condition, does it need a refurb? I think you will have to be the judge in this case because it depends on how much the potential buyer is prepared to pay to reunite this head with this car.

Good advice, thanks Mike..
