Hi Frank,


Yes Frank the heads were recieved complete.
I was told that the heads I purchased were from a 1975 450sl.
They do have manually adjustable valves.
The dfference in the heads I purchased and the heads on the
car is the added air chamber running horizontally under the valve ports.
The intake manifold from the car does not cover it when installed.
Were there 2 different intake manifold and head designs for the Mercedes d-jet fuel injection systems? I have since resolved the problem by having the original heads machined and installed. But the question still remains unanswered and I have set of machined heads without a matching intake manifold .
