FS: NOS?? 76-77 930 911 turbo mfi cylinder heads 9301043412R K196F

The consensus is that these are probably not NOS. These are beautiful Turbo heads. There are no cracks, broken fins, residual carbon or any other signs that these were used.
I was able to purchase all his 911 parts and I will be posting most of them here first. There are two that are dirtier than the rest and if you look at the first picture you’ll see why.

I’m not exactly sure on a price of these so I will throw out the number of $2000 or best offer. I’m sure if I’m too far one way or the other someone will let me know.

Jos,
Measure the int ports; that will confirm whether they're 930.
The studs you see are exhaust studs, not intake. The intake studs for 930 are exceptionally long to accommodate the injector blocks and manifold.

Those are not MFI cylinder heads. They're CIS heads with EGR bores in the exhaust ports.
MFI was not used on those models.

Jon,

Actually Bosch considers CIS a mechanical system. They refer to it as such in their workshop manuals.

Jos is correct.

OK Frank, CIS = MFI, got it...

Pretty sure you could whip me at Porsche Jeopardy any day of the week Jon so I’ll gladly accept the temporary trophy.

I can’t prove that these are NOS but the gentleman that I bought them from said they were. The only reason I question them is because several have studs on the intake side and several don’t.
There are no cracks, broken fins, residual carbon or any other signs that these were used.

They appear to have been thoroughly media-blasted, based on their uniform dull finish, even in the machined areas.
From what I can see in the few photos, I suspect that they're not NOS, but still might be a very nice set of heads. They'd really have to be inspected in person.

Agree with Jon; these are cleaned up, used heads. I have an NOS 930 head and it's as shiny as a new penny.

Great opportunity for the right person. These don't come along often.

The intake port indeed measures at 32mm which is a nice confirmation. I will change the title accordingly based on the input. Thanks for the help guys.
