Hey all,
Decided i would knock this up to help people ID what cylinder head they have. The list is mostly complete and i should have it finalized in the next day or two.
If people could cross check with what they have on their vehicles that would be awesome.
The casting ID is located somewhere around cylinder 1 and is ia 3 number/digit code. Attatched is a pic of an RB20DET so you can see the casting number.
Cheers
