Hello, I Have two Zylinderheads from Okrasa, but I have no Idea from wich Kit they are! Can anybody help?

Okrasa 0 15-11 Sr 2 k2 S43S is standing in the Head!

Thanks

heve sent you a mail!

15 tells you they are 30hp heads

Don't know Sr 2 k2, I've never seen this before maybe they are later 30hp heads, I've seen later ones stamped Si2
maybe someone else knows the meaning of this number?

S43 is chamber volume, depending on bore, stroke and deck height you can get between 7.7 - 8.6 compression ratio


hope that helps?
