I don't think those are 289 heads. I think they are originally for a 221.

But with a nice port and polish job from Mondello's, I'm sure they would outperform a stock set of hipo heads hands down.

They are not Hipo heads,just a set of early heads that someone had ported.Do they have the D shaped chamber in them or later design?

There is more to this head than meets the eye. The casting number is C2OE-G, the casting date code is 3A23, it is cast with a 289 marking, and it does not have the valve spring recess seats. Everything is wrong, which often means it is a prototype. The jury is still out, but it might be a prototype to the late 1964 289 head.

IF they are prototypes (and this is not just a troll)

then having Mondello mess with them at some point could have altered them unfortunately

Okay, here is what Gino has. The underside has a configuration similar (but not exactly) to the late 64 and later 289 combustion chamber.

Note the C and S markings.

Here is a close-up of the C2OE casting number.

The G is on the end.

Here is the rocker arm side.

It is clearly cast with a 289 marking.

The date code is 3A23, which is pretty late for going to Carroll Shelby because the production 289 HiPos were underway.

The heads do not have the 289 HiPo valve spring seats, which were already in production for the 289 HiPo.

It is possible that these were castings of the Shelby 260 heads, but it makes no sense that they would actually be going to Shelby with a 3A23 date code. Shelby would have wanted the 289 HiPo heads. But, it would make sense if Ford was using these heads as prototypes for the late 64 289. I have seen other cases where prototype heads having a casting number from a previous head, but incorporating new combustion chamber shapes, so this head does fit that pattern. Possibly, this head must have escaped the factory, somehow. Mondello's machine work has complicated the issue. They were obviously setting this head up for some serious speed.

If anyone has any pictures of Shelby's HiPo 260 heads, I would like to see them.

Personally I don't believe these heads have anything to do with Shelby.I've raced a SS/L for many years and back in the 70's had and seen alot of SBF heads that racers sent to Mondello to have done.That's all he has here is a set of early model standard heads that somebody sent to Joe to get done.

>>all he has here is a set of early model standard heads<<

Not with a 3A23 date code. C2OE heads had long been replaced in production by the 1963 model year, which began in very late August 1962.
