There are 2 main types of fuel heads for these engines, early (Euro) and late (USA). The early model is black in color and made of steel while the late model is aluminum. Either one will work but the aluminum model had a frequency valve incorporated into the operation which must be eleminated if used on an early engine.
I'm guessing that the one on your engine is aluminum as the early black unit would have been stock. I'm also going to guess that your engine is modified and this aluminum fuel head has had the frequency valve/Lambda system deleted and then adjusted for more flow. If this is so take a look on the side of the aluminum body towards the base and see if the numbers "007" are stamped into the housing.
Can you post a picture of the engine?

I found the thread.
My assumptions were incorrect. Either that is not a 1984 Euro engine or it is a 1984 Euro engine with 1986-9 CIS and exhaust installed for federalization purpose. The USA catalytic converter has been replaced with a bypass pipe.
What is the type number of the engine (stamped into the case on the passenger's side by the fan, 930/xx)?

The type number of the engine is stamped into the case on the passenger's side by the fan, 930/xx). A 1984 ROW engine is type number 930/66, USA 1986-> is type number 930/68.

No this is not necessarily a bad thing, especially if the changes were made when car was federalized. Very easy to remove the smog stuff any time if you wish.

do you think i need to go back to the original fuel distributer if i can find one, and i am still riding the fence on pulling all the smog stuff off. it was not working properly and i am thinking it will cost more to fix then to take off. my mechanic said he thinks they tun better with the smog pumps on and i have heard exact opposite from others.

Good deal on the type number!

If your car is running well I'd leave it alone. Should you decide to do some modification that would be the time to assess the fuel needs and react accordingly.
I have these items in stock should you ever wish to change back to Euro CIS.

whats the benefits of the euro CIS? the car seems to run well, although i had and occasional miss in 2nd gear at higher RPMS. but running well is a relative thing when i don't have anything to compare it to.

Euro engines were all rated at 300HP. USA '78/9 were 265HP and USA '86-9 were up to 282HP.
The Euro CIS is capable of flowing more fuel than the US system therefore desirable for moderately modified engines (up to 375WHP).
If your engine runs well and you don't plan to modify it there is no benifit to Euro CIS.

The smooh finished cast aluminum lambda USA fuel head is alot more versatile then the rough finish painted black cast iron rest of world or euro fuel head.

The USA head can be adjusted to flow up to 20-25% over stock while keeping good low speed manners which is 10% -15% more fuel than the euro head is capable of because it has a more flexable synthetic diaphram that does the final fuel metering individually for each injector.
It is also quite a bit lighter and won't rust internally if water accumulates and sits in the lower chambers because it's cast aluminum rather than cast iron, and it can be used with the lambda controller to give better gas milage and pass emissions with air injection installed and working in some states if thats required.

There is nothing better about the euro fuel head. It got that reputation years ago because if you compare it to a stock USA fuel head a stock Euro head flows around 10% more fuel under boost.

But because the euro head has a stiff stainless steel metering diaphram/gasket between the upper and lower chambers where the USA head has a flexible synthetic metering diaphram/gasket with 6 individual stainless steel metering discs attached to it - one for each injector under each of the 6 upper chambers and injector line metering orifices, the USA head can be adjusted to flow alot more fuel under boost than the euro head.
If you tried to adjust the euro fuel head for much more fuel the one piece stainless metering diaphram will be dimpled downwards under each of the 6 upper chamber metering orifice's and ruined.

Taking all this in consideration the slightly newer USA lambda fuel head is better.
I know from experience because I have owned both and tried them on my car and kept the 20% over CIS Flowtech modified fuel head.
In my opinion the USA head modified to flow 20% over stock with lambda removed and a Brian Leask adjustable WUR to fine tune AFR's is the best CIS fuel head for performance.

The aluminum fuel heads for big Mercedes and Bentley V8's are also interesting because they are the same size as a 930 head and have 2 more fuel injector outlets machined in the top that can be plugged or used for an extra injector(s) with an electronic injector controller on a 6 cylinder motor.
