is it possible to get the older 2.3.4. android kernel for samsung galaxy s2 ?

Hi All,
I have been trying to download and try an older version of android on my samsung galaxy s2 phone.
I want 2.3.4 kernel in it.
When I searched in google, android downloadable sites and in samsung official releases, I am able to see newer releases, but not the old release that I am looking for.
Can someone help me with the link to download this version?

Thanks in advance,
Regards,
Kannan
