Does anyone know the difference between these two Barra I6 cylinder heads;
Standard head
Part no. AY6049A up to 4/04
Part no. BA6049D 5/04 on

And also -
LPG
BA6049C to 4/04
BA6049F 5/04 on

Turbo
BA6049B to 4/04
BA6049E 5/04 on

There is another tread like this one, but with a criticle error.

All the cylinder head part numbers are BA

I presume there must be a modification to the head during production after April 2004. But what could it be?

Anyone?

Well I searched high & low, but can't find a thing on any cylinder head changes.

Found some good articles though, here are a few;
