I am building a Leman's Spitfire and I want to get the correct head so I can run the right carburetor set up. I currently have an 1147 engine with just the 6 port, completely rebuilt but unfortunately, dual webers cannot be run on this head -__-.
Thanks!

I think / recall that there were like 6 of them in the world , or something like that . IE , unobtanium .

If you really want/need an 8 port you might want to look into a 1300 .

If you were really into it you could maybe CNC some out of a big billet of aluminum .

Oh, I thought they made quite a few but were just semi-difficult to find

colin,
More than 6 were made, but expect a looooooonnnnnnggggg search and a high price. ISTR SAH made them for aftermarket sales in the UK.
Best of luck,
Paul

If you have the time and money, could commission a custom head.
Nowdays with laser scanners, it's not so hard to capture a design, then use CAD to alter it to the desired configuration.
Once done, a 3D printer creates either sand molds or a wax investment casting 'plug', and the part is cast (Aluminum anyone?).
Still not cheap, but far less expensive than the legacy methods.

Realize that the 1147 8 port also featured a custom intake, since no production part existed at the time.

I might have misunderstood "the correct head", I jumped to a "correct" car and parts at a nit picker show . If you want something close to what they ran , a 1300 would be close but not "correct" , the nit pickers will say its the wrong motor / head / set up , etc . I on the other hand would say cool beans .

And if you do, make a number of them so you can recoup the investment and fill a big void in the availability of this item. There is a pent-up demand that remains unfilled.

You bet!
If I was a younger man and still had ambition, I'd do a startup offering such services.

For example, the Honda D16 DOHC 16v motor has virtually the same bore and stroke as a Spitfire 1500, makes about double the power.
But the bore pitch and head stud pattern is just enough different that it would be very hard to fit to a Spitfire block.
However, if you were to scan the head into a high definition 3D model, you could use a CAD program to move things around to fit,
while keeping things like the mating faces of the intake and exhaust ports, so that the Honda manifolds would bolt right on.

Custom bellhousing to mate motor A to transmission B?
No problem.

Etc ...

and I would kindly direct said pickers to how they could in fact become suckers. winking smiley

Why not use a 1296 engine. Look much the same from the outside, come with an 8 port head and manifolds for twin Webbers are available......

Nick,
I have seen just that done to "re-create" a Le Mans Spitfire using a GT6 as the basis. I felt somewhat disappointed seeing it. There were too many glaring differences to make it a convincing job.
All the best,
Paul

I have the manifold gasket off one here. Unfortunately the head is attached to a very Historic Spitfire here, raced by Brian Sampson in the day.
It is a works car, with alloy panels, and was owned by AMI the local assemblers of Triumph.

I do not know whether it was built in England, or came here as a kit.

I suspect the latter

The period shot of the car is courtesy of Andy Ansell, of Triumph Sportscars.
He looks after that particular car now.
