There are definitely cam differences between JDM and UK, and don't forget that 2006-onwards UK cars are 2.5l whereas JDM stayed with 2.0l.
2005 JDM STi has same cams and heads as a Spec C of the same year.
Have to be honest and say I'm not 100% sure when "big port" heads came in, but I think it was 2005.
It's a minefield!! And I've not helped much lol.

Early bugeye uk sti heads are also big port, then they changed to smaller port...
There also has been debates about spec c and jdm cams.. They are actually the same cam..
I wouldn't worry about small port vs big port... There is arguments in favour of both... I would concentrate on trying to get ones with no cracks... This you are going to find very difficult in itself.....
