Some of ... I was just searching the forum for help and got that post too, I will make the tests tomorrow as in that post and will let you know the results.

btw, thanks for your replies, as you may understand I'm a little lost: I'm in Portugal, not many cosworths here to swap parts and test them, ford dealers some don't even know what a cosworth is lololol and the ones that knows charges more than 60 euros / hour just on manwork.

I was also trying to get another L6 to test it, but didn't find any in Portugal.
