Hi guys got a bug wrx and have just purchased a sti8 bottom end I want to fit my wrx heads to this bottom end but don't know what thickness headgaskets I will need heads have never been skimmed help would be great cheers

 

IIRC the combustion chamber volume is the same on the EJ205 and EJ207 heads, so if the heads and deck faces are standard thickness then the standard 'thin' steel OEM gaskets will be the one's you need.
