I'm no expert, but I learned recently that if you take a magnet and place it on the inside wall of the cylinder it will either attach or not. If it attaches or shows that it is magnetic it is likely to be Nik. Others with more experience can tell you more details. I hope it helps.
Best Regards, Alex

Wow. I've never seen anything like that. A cylinder with no fins.
The only markings I see is the number 5 painted on. The other markings are for the cylinder head which indicate that it was made in Dec. of 77' so most likely for a 78' motor.

Looks like a 3.3 turbo to me, there's a pic in BA's book showing these cylinders. They only have fins on the bottom, not the top.
I'd be suprised if they're alusil, but the only definitive way (that I know of) to know is if you pull the heads and use a magnet.
