1.8t problems.

[rudeboi]

hi guys new to this site and was hoping for some help.
I have a mk3 ibiza cupra. the ayp block was naff so got rid and found myself and AUQ bottom end but the head that came with the engine is totally different it's an APU head for a passat i think. so on hunt for AUQ head which proves not easy. Question is do any other heads bolt on direct ?

If any one can help it will be greatly appreciated.

thanks

Will an AUm head fit ? stats all the same minus the ecu map i think but are oil holes the same?
