does any 2.0 bottom end fit or do i need a ABF bottom end???
i would fit a complete engine, your head is probably warped as you say. you could get it stripped and skimmed, but prob easier to find a complete engine rather than a bare block
do yourself a favour. get on to just vwaudi, theyre in theberton near sizewell. he's got abf's 9a's etc, i got 1 a few months back and its all good, cost 300 quid, and made 159.5 on kjet. u could have it running in no time..
