Just out of intrest. Would anyone know any information on this sorta head.
All the information i got was that is a test pre-production development engine cylinder head. Used in production in 2000 in the Astra 2.0 lt sport but was used in an earlier application less tuned.
This head has only had testing hours on it, near enough new.
Thing is its a wierd part no also, dont show up on EPC.
