Fitting v5 heads to an EJ257
 

Does anyone know what mods may have been carried out to a set of v5 heads in order to fit them to an EJ257?
Looking at the reciepts they have been modded and looking to use them on the 2.1 if possible to save having to get another set.

Cheers
Chris

normaly some machaning the combustion chamber to keep compression ratio sensable it also reduces the chance of detonation, which allows more timing to be used.

easiest way to see is to offer up a 2.5 gasket on a 2.0 head.
