Fiesta head legal?

[scorp997]

I think I know the answer to this question, but I will ask it anyway.

Is the head from a Fiesta legal in FF? The rules indicate that the Pierce aluminum head is and that the Pinto 'chambered' head is (for the non-uprated), but no mention of the Fiesta head. I assume that if it isn't specified, it can't be used.... If it makes any difference, it will be used on a vintage FF, not a conference or national car.

Besides the smaller valves and ports, are there any differences between the heads used on uprated FF engines and the Fiesta? I will of course have it built up by a pro builder, which will correct the valves and ports sizes. I would like to pick up a spare core and I have access to one locally if it will work.

Thanks in advance.

The fiesta head is legal. It would be a core head that a cylinder head specialist would port to be a race head. I imagine the cost of having the modifications done would be 3 to 4 times (or more - the cylinder head guys hate to grind on cast iron after getting used to nice clean aluminium) what you could buy a perfectly reasonable (although not state of the art) cast iron race head for. The only reason that I can imagine having a new cast iron head ported now is to somehow dominate vintage racing in your area...

Do you have an uprated, or a Cortina engine? I have a Ivey Cortina head, manifold and carb if that's what you need.

I have an uprated engine..... Thanks for the offer

The Fiesta head is not legal since it's not specifically authorized by the FF rules. You need either a standard uprated iron head or a Pierce aluminum version.

How can you tell an uprated kent 1600cc head that came on a Fiesta from one that came on any other uprated Kent 1600cc engine? Seriously. The last Fiesta engine I took a core from was a long time ago, and I thought the head was identical, to the part number. I use it as a jig to build headers on. Is there a list of casting numbers that are legal somewhere?

Uprated head casting number is 711F-6085-CA.
