    Just above intake manifold over intake port for cylinder 2 you should see 051103373D.
    This is the mark of a late head casting found on ABF engines from 92 to 99.

    where can I find the part no for the head of my kr? (it's in the car already, can it be read without removing anything)?

    thanks

    You would need to substantiate those claims back to back. 027 103 373 E heads have larger inlet ports as they do not have water cooling in the intake ports, this changed with the introduction of the later 051 103 373 head and remained with the latest 051 103 373D head. Biggeer inlet ports of the 027 103 373 head does not make it "better".

    As all of the 16v heads have the same combustion chamber volume to all intensive purposes as std, you are incorrect in saying that it lowers the cr when fitted to an ABF engine.
    The shape of the chambers differs as mentioned previously due to the differing bores of the 1.8 and 2.0 but the volumes remain virtually identical.
    Unless you have volume checked the chambers first, it is not useful to post up incorrect data.
    Basically the std 16v heads all have a chamber volume of approximately 45cc + or - 1cc to cover production variations.

    Hmmm, just had a quick read through this after looking at a 9A casting last night and the existence of the "casting number" which is not equal to what I assume is the ETKA number reads like engine block casting numbers all over again (ETKA lists short engines with cranks etc, whereas the casting on the block is a different no again).

    Surely from a practical perspective, we need to map real casting codes to ETKA codes, since folk will mainly be presented with the physical item and be trying to identify it!

    Pls correct me if that's not the correct take on this!

    You just need to spend more time mucking around with 16v engines. ;)

    The head casting numbers are no use in describing the whole head assembly as different cams can be fitted to the same heads.
    eg 051 103 373 D is found on the the ABF engine and also late 6A ones too. The inlet cams are different in them though.
    Also the 051 103 373 heads fitted to later KR and 9A engines, different cams again.

    "Mucking about" !! You cannot speak about an epic engine like this in such undignified terms! Shame on you!!

    Ok, so we have complete heads, with cams specced and a part no for that assy. So if mixing & matching complete heads without a rebuild, that gives a head picking guide.

    You can see where this is going... [STRIKETHROUGH]IKEA[/STRIKETHROUGH], I mean a table.

    It would make a stack of sense to have:

    Entire assy part no Head casting part no Cams fitted + part no Comments
    .

    And then

    Head casting no Original engine/engine found on Head features
    .

    You knows it ;)

    Guys, how much do you reckon I'd have to spend to build a 051103373 cylinder head from a KR engine? I do have the cylinder head already + cover + intake + throttle body. But all the other parts, I don't. Do you guys have an idea of a ballpark at least?

    This is not really a place to discuss prices, as the quality varies widely as does the cost for what you get.

    Contact your engine shop for any details.
