Hey Guys,
I've got a couple questions regarding a smallport 16v complete cylinder head that i've been given by a friend.
A little bit of background info on the head and my car,
Engine was a 4age 16v smallport from an ae93 gti.
The engine was swapped due to a cracked block, my friend claims the new motor never went as well as the old one.
He seems to think the old motor may of had aftermarket/larger cams fitted due the way it rev'd/went after 3000 rpm.
I have an early 4age 16v bigport 16v in my ae71.

Question 1: Is there anyway visually or measuring to comfirm if the cams have been changed ?

Question 2: If the cams have been changed is it possible for them to be fitted into an early 4age 16v bigport head ?

Question 3: Will you need to swap all the shims and bucks over aswell ?

I know that you can fit bigport cams into a smallport head, but i couldn't find any info if you could do the opposite.
I'm guessing that you could do it.
Thanks Hayden.
